Which is preferred? I have a line on a couple Kohler and Briggs opposed twins I could swap in my wife's hustler 960, just not sure which to go with, my Bigfoot has the Briggs ic I'm considering going with a Kohler on hers just to see how much if there's any difference performance wise. Hers is geared different and has smaller tires but that may help even things out. Shes getting a red spring on the driven also since it's originally a 2 stroke Kohler twin k440-2am. I had plans of stuffing 25s or whatever fits and regearing but she just wants to go with the 22inch tsl and just make hers the mini of the Bigfoot. Bigfoot has 26 inch tsl. She calls them big Dipper and little Dipper, shes into astrology and horoscopes and stuff and I guess that's our constellations idk lol, way off course, which opposed twin would you guys with more experience go with?
