"I train mainly for hypertrophy, not strength"

I don't want to tell you how to train as your body knows you better than I do. But it doesn't look like you are optimally training for Hypertrophy. For that you would do 1-6 reps with max weight... Regardless, monitor your flexibility and have a good spotter!
