Love all the high pulls, hang cleans, and just straight cleans from the floor etc Trebor, although that does look a bit 'mad' tbf lol.
Pretty much agree with Pagan on this one, I go with a more linear motion, and hand spacing and where you pull the bar to can make a big difference on how much the shoulders play a part as well, I use them mainly as a shoulder/back exercise and basic core/explosive stuff, so although I do get momentum from the floor using legs and lower back, I try to focus on the final half of the lift and let back, traps and shoulders do a lot of the work.
Give it a few weeks mate and you'll be surprised at how you begin to notice certain body parts have added a little more muscle than the conventional exercises, I always notice a big difference around the lower bicep/forearm area as well as the rear delts and back/traps.
