I never give lifting advise and this is just what I started to do after some reading.
Like you I was using a decent weight and repping the shit out if it and yeah it's a good workout but if you want to get stronger and bigger on CNS I'd drop the reps and raise the weights for a few sets at least.
Here's how I lift now.
Squats
225 5x5
275 5x5
325 5x3
225 3x8
225 2x10

Still lots of reps but I have one working set that's taxing. Oh and I don't do ANY CARDIO.
