Pro's / cons different Swivels for Big Guy

Needing to replace my swivel. Heard the new swivels Whisper Wash make are real easy to repair (cartridge). Also considering using the Mosmatic 3 or 4 bearing swivel but heard there are are repair issues (getting bearings etc...) . Is the Mosmatic 4 bearing all it is hyped up to be....Faster and smoother? What about service life? Also how does the 3 bearing MM compare to the original WW swivel?

The mosmatic 3 bearing has run perfect for me and spins like butter, just keep some pure silicone grease in it. I don't know if its different but the mosmatics have plates with ball bearings plus a sealed bearing, better than just sealed bearings I think.

Second the mosmatic! Def the way to go! A mosmatic in a big guy is perfect.. The factory swivel that comes on the big guy can't compare.

Mfrs, dealers and service guys in here appreciate the feed back..
example with the opinion is great !!

I have the new wisperwash swivels in both my maxima's. They have been in there for over a year now and no problems at all. Not even a leak. The old ones would never last that long. We use them at least 5 to 6 hours 5 nights a week.
