Tri Gear for the Big Guys?

Im 6'4" 240lbs and I was looking for some tri gear this weekend. I found out that I do not fit into any of the tri tops that they had at the local store. What do you guys wear? I was thinking of using under armor Heat gear. Another recommendation I had was a sleeveless bike jersey that wasnt quite as tight fitting as the tri tops.

As far as shorts go I think I will be alright with just some regular tri shorts but I was wondering what most of you long legged clydes wear?

Thanks for the info.
Mike
