Road Cycling - Mid level racing wheels - help to choose

Here's the list i am considering. i am 75Kg doing triathlons and looking for a clincher type. Prices are ebay’s, no cassette.
1. Bontrager - Race lite: not so deep rim (23mm), a bit heavy (1745gr), ~$350
2. Rolf – Comp/Pro: I have no idea. Could not find data/spec. I heard there are good, but they are not manufactured any more, ~$350. is there a difference between the Comp nd Pro? which one is better?
3. American classic 350: light (1362gr)!,no double rims, not so deep rim (24mm)
4. American classic 420: light (1420gr)!, deep spoke (34mm), no double rim
5. FSA – RD200, RD400: have no idea, are they good?, ~$300
6. Mavic – Elite: a bit heavy (1770gr), no double rim, spoke not so deep (25mm), ~$350

What would you choose, for racing only. i hoped to have a complete set (including tires and cassette) for less than $500. i am not an expert but want to go beyond average of 20MPH. other suggestions are most welcomed.

#4 AC420 stands out for triathlons from your choices. Aero is important and it also is one of the lightest of your choices. AC also has a good reputation and is easily trued and repairable if need be.

I would stay away from the Rolfs. They are crap once they go out of true. Rolf finally redesigned them this year to improve the technology.

What do you mean by "no double rim"? Also by "deep spoke" do you mean deep rim profile?

Sorry for the mess... yep deep rims or rims height.
Does it make a different if the spokes are spread equally or in pairs?

less spokes is less weight...but there are other trade-offs for that, like durability and strength.

if you already have wheels for your bike, use the race wheels for racing. Use the other wheels for training. lighter is not more durable. Heavy is generally going to take more of a beating at this price level.

No.
Theoretically the paired spokes are more aero but to make it work, you need to overbuild the rim. This creates more weight where you don't want it. They are very difficult to true or rebuild too. I'm not a big fan of Rolfs or paired spoke wheels in general.

From experience, the only ultra-minimal spoke wheel I like are the Dura-Ace wheels. (not counting Zipps or other low spoke count wheels)

Evenly spaced bladed spokes are very aero and stronger without having to beef out the rim. That is why I like Zipps and the reason why most, if not all, aero wheels keep evenly spaced spokes. That's my experience anyway.

In tri, aero is more important than acceleration so rotating weight is not as crucial- but it could be significant if there are rollers or a long false flat. You want weight concentrated towards the hub, not the rim to minimize rotating weight.

If a wheel weighs 1500g isn't as important as what the rim weighs. I would rather have a heavier hub and light rim (carbon wheel, for example) than a light hub and heavy rim (Rolfs). Even if these 2 wheels weighed the same, they would accelerate and handle very differently.

A lightweight wheel with aero profile is a good compromise in tri. A bit heavier rim but cuts the wind better and keeps your momentum up but still light enough not to hold you back on climbing.

As race-only wheels, you want lighter and faster. Only the AC wheels qualify from your list.
To be honest, the other wheel selections don't seem to suit tri's anyway. AC makes good stuff so if you can get a good set cheap, I say go for it.

My 2 cents. Good luck!
