Erson roller rockers, opinions?

Hey guys, wondering if anyone has had good or bad experience with Erson 1.7 pedestal mount roller rockers P/N E-928089? This will be my first ever Erson product to use so I was just researching and trying to get some feedback from users before I made the purchase. :nice: Thanks
 
Havent had any run ins with those on small fords, but being as erson has been around for about 400 years and have used there stuff decades ago with great outcome, I wouldnt hesitate to use them again. You will be in a very small circle of people using them. I know of noone using them BUT theres nothing wrong with not playinh follow the leader.
