Thanks for the input everyone! I've talked to both of them about it, particularly with asking T1 to push harder but I think she always falls back into her "style" because that's who she is (and that's cool, because her style has some uses!).

I think I'll stick with T2 for a while and see how it goes. I don't have the knowledge of discipline to push myself, I need a cheerleader or someone to challenge me.
