Doubting Thomas.
One thing you could try is to reduce your reps and sets. Work up to a top set or sets of 2 or 3 (with a corresponding increase in weight), instead of 3 sets of 5. This will maybe slow down the hypertrophous ass while keeping your strength up. Another thing you could do (as you suggested) is to try front squats one day per week and see what happens. Don't stop squatting.
