Wow.. feel like a got flamed for no reason lol.. didn't mean to offend you or anything, just trying to help/ give you some options! I thought you mean you liked going light to focus on the hips but I obviously misread!
okay so what you meant was when the weight is light (when ramping), you don't use your arms as much (because you hip drive is enough), which I understand, and I used to do that when training explosive pulls for sport (wasn't really interested in lifting back then), but I quickly realised that by taking advantage of the light weight, you allow your WHOLE body to progress through the force spectrum and warm up /activate the CNS more efficiently.. also better for technique to engage the same muscles for every set.. obviously you said that you've been doing these lifts for years so i'm sure your technique is pretty damn good already.
Seriously though, I think your results on the layer system, speaking about high pulls here, will come quicker if you engage the same muscles/technique and progress through the force spectrum up to you max.
Last point; i think the layer system will definitely get you stronger, more powerful and look awesome! haha.
