Gentlemen, great replies; I really appreciate this.
Mike, heavy MP's complements my pull ups uniquely. But I do it like 6 pull ups with 20 kg between legs then resting quickly to 1 or 2 50 kg MPs.
Stefan, I always use the thumb rule grip for chins and pulls. But I'll definitely give other grip variations a try.
Reinhardt ( from dragondoor, right?), I've actually got hooked into kroc rows very recently, like a week. Before, I was always reluctant of kroc rows as the form seemed dodgy.
Thanks
