Hi, I'm looking to get some aero bars to mount on my specialized roubaix compact for triathlons. I was looking at the profile design T2+ and the profile design aerolite and I can't decide which to get. The T2+ is lighter and provides for a more aggressive position but I have read that some have wrist issues on it. The aerolite is 200 grams heavier but seems more comfortable because it doesn't use the s-bend. What do you think? Thanks.

Also, if i do buy one of these, what should i do in terms of positioning? Should i just get a basic fitting from my LBS for 35$?

I'm not an S bend fan myself. Perhaps if I were pro and looking for every possible aero advantage at the expense of comfort then maybe I'd go that route. If I'm not able to maintain an aero position for a long time, then it doesn't matter how aero the bars are. I'd rather be comfortable and stay aero than uncomfortable and having to keep sitting up to stretch.

Also, if you trust your LBS to know what they're doing fit-wise, spend the $35. When I first bought my TT bike I adjusted the aero bars myself and rode for about two months before I had time to go in for a fitting. I thought I had them dialed in pretty well, but the fitter made a couple small adjustments and the bars became much more comfortable for me.
