I have never used one, but my best turkey hunting bud does and he loves it. He has used it for 10+ years with Nitro shells and has never had a reason to change. I have never heard anything but good stuff about Rhino chokes. With that said, I did notice Rhino came out with a more economical "thunderbolt" version this year for $49 instead of the typical $98 "Grand Slam" model.
I have a pair of rhinos and a pair of kicks so can vouch for both (though only the kicks out of an 1187). Both are darn good chokes that get the job done but the rhino is a bit more expensive and often has a wait time if you have to get it made vs kicks that can be in your mailbox in 3 days.
