Have you ever thought of doing explosive high pulls and just forgetting about the catch? Your benefit is in the pull, and I think any eccentric benefit is highly mitigated by your catch form. So why bother with the catch?
Some one has mentioned to me before just doing a high pull, i could do that. So doing full cleans is no good either? I have tried them a couple of times and have ok technique, but obviously the weight moves slower when its 15-20kg more.
This is why i normally train with 140, i catch it nearly straight legs, so no errors. Either way, I wont be doing any training at all for a while so i might as well start planning now.
