 Brent is using these lifters on my build and has experience with them. When we were choosing the parts I spoke with an engineer at Isky and he claimed they have test data that shows these lifters last 2-3x (or more) roller bearing lifters, and several of the guys at Isky use them on their daily drivers (I guess that's why they work at Isky) and have 40-50k+ miles on them with normal adjustment. It certainly sounds like a good design idea to me.
