I would just call up Tony and see what frame and what size he recommends.

What I never got around to saying in my other message is that you could buy a complete Mark V for $400, then still have money in your budget to select some different parts. Or, what I would do is save the money I didn't spend, ride the bike the way it came, and then decide which parts need upgrading. I especially lean this way because a complete, pre-built Mark V is LESS MONEY than a Mark V or Phoenix partial build. The main reasons that I would encourage an IRO complete are: the customer service, the guarantee, and the wheels. I don't know if anyone here knows for sure, but I have heard the IRO hubs look a lot like Formulas and the rims look a lot like Velocities.

I don't know much about the Phoenix. I was on an ill fitting Angus, which was why I sold it. I recently sent Tony a message and he said I should have tried a larger frame. I think there are some members riding a Phoenix, but there are a lot of members riding Mark Vs.

I have been riding a while, and I am in the middle of a build project myself. Some of the time I want to just sell everything and buy one of those Mark V's for what this next wheelset build is going to cost me.

Now, the Phoenix will accept larger tires, but I think you will be plenty comfortable riding a Mark V. It is a little tighter than most road bikes, but not as tight as most track bikes. For me, this meant more fun to ride than most bikes.

I wouldn't worry that much about your weight and the bike, but I would worry more about getting a good fit. Any properly built wheel with enough spokes should be fine. I weigh >200 as well, and the IRO wheels were always fine. I rode 23s and 28s on mine and never had any issues. I think you would be fine on 28s.
