I'll give the 3/3 and 2 sets only a go. If I'm used to being slightly faster, will I need to drop the weight a bit, in order to complete a similiar amount of reps?

I think I do already push myself quite hard though. I'm quite stubborn and refuse to quit, so I always aim for that one more rep. Especially as I know I've only got that one session to kick start the growth for the next 48 hours.
