You make a lot of assumptions about my choice. Truth be told, I know a twin fits my riding much better than a triple. For starters, I'm a fast trail rider and former snocross racer. I want a compact sled with great balance, and the ability to change direction quickly. Low end power and acceleration are more valuable to me than smooth power and high top speeds.
A newer twin, like the skidoo 850, offers great fuel/oil economy and performance with a single pipe. A triple of comparable power uses three pipes, and eats fuel in comparison. Add in extra weight, and more rotating weight in the crank, and you have a sled that doesn't change direction as easily or handle rough terrain as well as twin.
I've had triples (thundercat, formula 3, xlt) and they were ok for their day, but not for the way I ride. The f-III was a good lake sled, or UP groomed trail ride. Fast, but not good handling. My F6 Snopro with stock F6 efi was just as fast but much better handling.
I couldn't care less about marketing. I buy what I like, and what works for me. Having 7 sleds, I can pick and choose a sled for what the day holds. Touring 2-up, vintage, ZR440 racer, 600 mountain cat, mod 600 snopro racers, and a Nytro which I bought on a whim to see if I liked it.
We can all have our own opinion without getting butt hurt and becoming keyboard cowboys. Mine is based on knowing what I need from a sled to enjoy my riding. In 37yrs of riding I've been able to determine that for myself. If you like triples, good for you.
