Have an artificial shoulder joint that I have to protect. Basically if I hit the wrong way and my upper arm shatters where it meets the titanium joint I am done riding, and a lot of other things, forever. Found a good article on Thumpertalk years ago about combining hockey shoulder pads with our chest protectors. I did it and it works really well. The hockey guys whack on each other with sticks, and crash hard. So they have excellent shoulder/collarbone/upper arm protection. We have good chest/back protection but poor shoulder. This combines the best of both. I will post a pic later and you will see what I am talking about. Mohave
