tri spoke vs hi profile aero wheel

a deeper "normal" wheel will have a more steady feel to it, where on a trispoke you will feel the gusts more. Honestly I wouldn't "train" on either (although the trispokes are pretty much invincible) but ymmv.

You can also *optimally* run a wider tire on most of the deep wheels available nowadays, and since bontrager stopped making the aerowing it's going to be increasingly more difficult to have an "optimal" set of trispokes without some hunting.

I ride with tri spokes on about half the time. I weigh in the 180# range and have no trouble at all controlling the bike with the tri spokes on. Wind around here is fairly moderate, but we do get some gusts, especially in the winter. Most of the roads I ride do have some shoulder, but I've never felt having the tri spokes on has resulted in any sort of safety issue. Handling is a little different than my regular training wheels, but I would not describe it as unpredictable.

I've not ridden other deep wheels, so I can't say how handling of the tri spokes compare to them.
