Solid roller cam Vs Hyd flat tappet

I have been running a sol roller in my GTO for over 20 yrs. I try & drive it at least once a week. I check lash every 2 yrs. I got over the boy-racer stuff a few years back, so I don't beat on it much these days. Only thing I would add is to use bushed lifters. I have the Iskies...not cheap....but worth it.
