It seems that some people are confused.
6'2"/175lb (the original poster) is just fine for a 150/152.
6'2"/210lb is also fine, depending on instructor weight, and how much fuel you take.
I'm 6'3" and (was) 175lb when I trained and instructed on 150's. Fitting in a 150 was never an issue. It's cozy but not really cramped. I actually used to enjoy flying the 150 more than the 172. When I spent a whole day in the air, however, I would often yearn for the relative comfort of a 172's bigger and softer seats.
I have always thought the 150 to be the superior trainer. WHY?
It is more demanding of smoothness from the student since it is more responsive. This responsiveness, in turn, leads the student to have a better "feel" for the airplane (which is what flying is all about, isn't it?). With regards to the 150 being easier to fly in gusty conditions: believe me, if you can land a 150 in a 15 knot crosswind component, you can land a 172 in the same. Finally, the little 150 is just plain more FUN.
