i fell in LOVE with the nytro the day i rode it. i've always had a rev and last year was on a very lightweight apex (no boost).
i put a boondockers turbo (the garrett 28) on they nytro recently and originally had it set at 12 lbs. my front end is stock with fox floats, i have the gen 2 simmons wide skis and a timbersled rear 162" skid. i put the challenger xtreme 2.25 track on and a tunnel extension. snojunkie rode my nytro then dan bush's mcx nytro 2 weekends ago on a typical spring day. i didn't have my sled dialed in at the time, the clutch weights were set up for 15 lbs of boost which is what i set it to last week and its a totally different (and better) sled. getting the rpms up in the 8900 range instead of 8K where they were. btw...dan bush's mcx nytro is one of the fastest sleds i've ever ridden...and i've ridden some pretty bad a$$ machines. his sled is just completely dialed in and dan is a great mechanic.
coming from an m1000, the nytro is going to feel like an alien spacecraft. it just is. like anything, it takes a few rides to get the feel down. also, the nytro can be set up (like any sled) to a very specific riding style. i have a TON of ski pressure on mine to keep that nose down once the boost comes on. i'm not a big fan of the wheelie. it looks cool for about 3 seconds but it is the tell-tale sign of a improperly set up rear suspension. the timbersled rear is great and very adjustable to handle a tipsy nose under big boost. the downside is that on the snow, putting around or in light boondocking, it feels like a tank. add to this the gen 2 skis on spring snow and you've got your hands full.
in the trees, i LOVE this sled. anyone who says a turbo nytro can't boondock either hansn't really ridden one in such conditions or is just making stuff up. the mid and low boost pick up on top of the already great stock throttle response is a dream in the trees. there is no doubt that riding a turbo sled takes some practice. you learn to anticipate the power, when you want it and how to deliver it.
the bottom line is once you've gotten used to these things, the up-side of having strong, reliable power in a 4-stroke motor with no tuning or tweaking is totally worth it to me. but all of this is a matter of preference.
i rode a tricked out rev summit last week with a trygstad 880 that felt like it weighed about 100 lbs. this sled ran neck in neck with a turbo dragon 700 and was an absolute blast to ride. there is just something about a strong, light sled that rips like that.
just ride what you feel good on. all these sleds kick it pretty hard.
