Dont know if this helps but i recently sat down and went through the same thing. I didnt want hard shell protection, to bulky, to hot, and to restrictice to ride in and i didnt want a light weight top that didnt offer enough protection. I looked at loads of options from the motor bike stuff like forcefield to the oneal sas -tec stuff. Sas tec make the vpd pads for poc so the oneal stuff was top of the list. However due to time and availability i went for this
http://www.chainreactioncycles.com/Mode ... elID=82726I wasnt to sure how it would work out but having done a week of uplifts at the forst of dean and cwmcan its amazing. No jazzy d3o or sas tec just the same pads they stick in american football and hocky armour stitched into a breathable mesh top.
It feels comfy and to my amazment it stayed in place percectly. You can feel air moving through it and its comfy enough to wear without restriction so i could wear it where's my mates had taken theres off or just wouldnt put it on.
Most inportantly i binned it hard and very fast down the side of cwmcan twice and didnt realy feel a thing. The first was a full face first superman with me shoving the bike away in the air and lading hard face down and enough to smach the visor of the helmet and i walked away compleaty unscathed.
Im not trying to oversell this but i thought id share as it worked so well, and a lot better than i thought it would to be honest.
