I'm having excellent results with the Mr. Hop. I haven't tested the X range and likely won't unless one drops into my lap.
Looking at the comparison photo it kind of reminds me of a mix between the TNT TR Hop buckings and an autobot. Neither of which is a bad thing. Potentially requiring permanent barrel window modification is a turn off to me though.
Having not handled the modify, I can't say with certainty, but the material looks very similar to the silicone used on the Flamingo buckings I tested. I was not impressed with those at all. The material on those also took on permanent changes after being installed with hop pressure added for as little as a week. I can't say if those changes negatively effected the performance, because the performance was never good, just something to consider.
I'd be interested to see testing with them and a comparison. Be tough with the barrel modifications that may be needed.
