At least for now, it seems like it may be more what is available than anything else. I initially had a set of Morels for my motor but that was because I couldn't find anything else. Those had lots of negative reviews so I kept looking and eventually Butler had the Johnson reduced travel lifters available so I grabbed a set of those and sent the Morels back. The Johnsons are in the motor so we'll see. I will say they are very quiet, whatever that's worth. Standing right next to the motor on the dyno, really no lifter noise at all.
