We have used them a ton. Never an issue as long as you check the torque periodically.
We use a different brand with the same high quality and a little better price point if you are interested. I keep some of them in stock or can get them pretty quick
Yep, I run them... no problems at all. But you might want to talk with Andy (CRS) unless you have your hands on some Spidertrax ones b/c they're never in stock.... You pretty much have to buy them used...
