Training SQ/DL For Squat PR

Today i hit a 50lb squat PR. 600x2 @ 201 bodyweight. I wore a very loose inzer hardcore single poly suit, wraps and a thin belt. It was walked out. I feel pretty proud of it. I am 26 years old.

I have been training the squat every other week, 5x5, and deadlifting the other weeks in between, 3x3. I feel this has really increased my squatting power a lot. Just wondering if anybody else has trained the SQ/DL like this and if so, how did your progress go??
