I have said the same thing you said before, because I thought I was having similar problems. I wish I had never cut back my squatting momentum then, it is NEVER a good idea in my experience.
1) Post pics of your legs
2) What do you squat, using GOOD form?
I think most jeans are just undersized for people who squat, that's a fact. Would you be complaining if you were growing out of shirts? Of course not. Just find stuff that fits. Visually, huge legs will never unbalance your physique unless you want them to. You wear something over your quads all the time, it's just not going to unbalance your physique like bad posture or a huge belly or something.
I suspect you aren't quite as big legged as you think...I also think if you wish to grow, you need to take growth where you can get it until you stop getting it. Believe me, your legs won't grow forever. Keep hitting them hard and they will slow down soon.
