While the majority of us love to support disc golf businesses, straps will always be available. What leads me to say this is that Menards sells a set of gel straps to contractors for about $20 bucks. I personally know 2 golfers that use these straps very successfully. They've used them for a few years, they are holding up fine, are very comfortable. While I have 2 sets of quad-shocks, I have checked the others out at the store and if the need arises, I will probably choose those when looking to purchase another pair.
I have them on a latpro bag and they're very comfortable.
