I used these:

They work great. I sold my SxS, but I still have the pair. If anyone wants them PM me. I think they're probably worth $20.
Ended up getting the shock straps. Looking forward to trying them out and giving a review on here for others to see.
Well, after using the shock straps quite a few times already, I must say that they must be the best on the market. Well worth the extra money, no question. Haven't had to adjust my load once and I have put them through some good tests.
