Well, I've finally decided to get a power meter and train properly with a coach. Since I'm fairly set on picking up a powertap (SRM/ergomo/quarq are too much $$$ for a student), I'm now stuck with a choice on whether I should:
a.) build the powertap into an open pro (new rim or prebuilt), or
b.) tear apart my Flashpoint FP60 summer project from last year and build the hub into there?
The flashpoints are laced in a 28-spoke clyde config with sapim cx-rays into a white h1 hub. I went with that lacing even though I'm only 155lb just so that I could train and race with them all the time.
Given that I have no major qualm about training/racing my flashpoints to begin with, is there any reason that going with the open pro would be a much better decision? I'm thinking that it'd be worth the loss of having a bunch of $$ spokes & white hub sitting around unused than not using the entire thing completely. Anyways, would love further insight - thanks =)

I'd go with the Open Pro option. The FP60s are heavy enough as it is. I reckon adding the Powertap hub would push them over 2kg for the set :eek:

I'd go with an Open Pro too. Don't take apart a perfectly good set of wheels, you never know when they'll come in handy!

Replacing the hub in my current set would result in a ~1871g wheelset (vs ~1700 currently). All of the weight difference, however, would be at the hubs.... 416g for a SL hub vs 245g on the white H1s.
Thanks for the great feedback though, I missed thinking about weight in the midst of the "I'm buying a power meter excitement." :D
Keep it coming everyone :)
i'd go the flashpoint route. the weight is getting up there, but there are studies indicating that aerodynamics are more important in a wheel than weight, even for climbing. if you're gonna use the flashpoints for training AND racing, why not put the PT into them and get the aero advantage as well?
I would do the open pro route. I like having a wheelset for training, and a separate one for racing.
One reason, lots of flat tires are caused by junk you picked up on a prior ride that works its way through your tire and punctures your inner tube on a subsequent ride. Having 2 wheelsets, you have a training set that you can put some hard more puncture resistant tire on, and on your race wheelset you can put grippier but less puncture resistent tires. Unless you enjoy changing tires all the time, IME, that's the way to go.
Also, it's difficult to have too many functional wheelsets.

the sperm velocity deep v!
but seriously, i guess my opinion would be to go with the flashpoints. if it were me, i would just race on the flashpoints and train on something else, but if you are confident that you can do both racing and training on those wheels, i say go for it. the weight penalty is not very significant for races, i would say for anyone, the powermeter would be an advntage over the weight increase. it sucks to tear apart your old project, but that is the price you pay for training and racing with power. good luck!

I voted Open Pro, but I don't actually recommend that rim. You can do better for the money, or do just as well for less -- of course the pre-builts may be too sweet of a deal.
I'm really really happy with my Velocity Aerohead OC / PowerTap. The NDS tension is over 70% of the DS tension, so it's a great tension balance. Get a 32h, and at your weight, you'll have a very durable setup (more durable than an Open Pro).
Alternatively, one of those Kinlin 30mm niobium rims might be tall enough to look better with the Flashpoint front. They come in about 60g heavier than the Aerohead OC. You wouldn't need 32 spokes though, at your weight (28 would be plenty). You can read about a build I just did with the Kinlin here (http://www.bikeforums.net/showthread.php?t=381303).
Anyway, keep the Flashpoint built up as it is. You never know when you'll need to send the PT off for service. Down the road, you might look into getting a used PT hub for the Flashpoint though, so you won't be tempted to race on it and miss out on the data.

I vote Open-Pro. Judging from my own experience and anecdotal evidence from most other people, it seems that OP rims are one of the better choices for handbuilt wheels, for either training or racing. Once I settle an accident claim from a crash that I was in, I'm going to invest in a PT, and I'm fairly certain that I'll have it laced to a OP or equivalent. I was considering going aero and tubular (a Zipp rim, etc.), but that really doesn't make much sense considering how much training I do on ****ty Chicago streets.
I second waterrocket's idea of buying a PT hub for the Flashpoint down the road, or even buying a lighter rim and using that instead.
You have a lot of options – think most about what kind of riding you do and where you do it.
I lean toward the Flashpoints. If you are planning to train and race on them then why not? You could still buy a lighter set of climbing wheels down the road. The advantages of power and aero seem to outweigh the weight.

you can get power data when you're racing or riding hard.

+1. I'd build it up, so you can race it. Your best data will come from races. Don't see the point in having the Flashpoints just laying around unused.
If you go the Open Pro route, I'd consider ebaying the Flashpoint Wheels.

Go with the Sun Attack at 405g. If I'm going to build a clincher wheelset, thaose would be the rims I'd use. They've also for a 26mm deep alloy rim at 440g.

Flashpoint for sure, especially if your stated intention for those wheels was to have a training AND racing wheel. They're not THAT heavy.
Caveat: I'm about to do the same thing, just debating about whether to keep my current PTSL/CXP-33 setup.

Search on WW for the thread about Gipiemme Tecno 7XX (16 or 21 or 31 or something) rims.
They're the OLD Campy Shamal rims, in 40mm depth, and either tubular or clincher. Pretty much any drilling is available through the distributor.
Fast training wheel, but saves your race wheels for race day.
