Sounds to me like a tri specific geometry is just not for you. I'd sell it and call it a day. Just because all the other "kids" ride on doesn't mean you have to.
Love the one your with I say...
It's hard to find a bike that fits you as well as the trek does, so no need to cast her aside.
Just my opinion and all, but heck I say don't pressure yourself to ride tri specific if it doesn't work for you.
