Those are some good comments. I personally love squats, but I also love KB stuff ;-)
Maybe I might try KB sumo deadlift high pulls, wich are very "squat"ish as opposed to swings.
I just like mixing things up and normal squats tend to be to easy compared to the rest (I have pretty strong legs from playing drums for many years in a few rock bands).
Thanks and cheers,
