I agree with your statement about the smaller fuel tank. But i eventually got over it. I have never had to second guess mileage on either a 850, or my 900Ts. Mrs. Turbo Doo also does not like the fact that in order to get a 4 stroke, you need to go to a Renny. But i am thinking her 2018 MXZ Blizzard 900 will be for sale next year, she is leaning towards a 900T. I also really enjoy riding her sled, which is like yours. With the new Ras X and R motion X, on this year's '21 Renny XRS 900T i have, i am willing to bet it will be a definite awesome sled. If you get a chance, ride one. Wind protection with the proper windshield is good, albeit not as warm as a XS chassis. A proper set up G4, ultimately is better then the XS in handling characteristics. Body movement and positioning, at least on my 850s, changed alot of characteristics of the sled. But as you stated, your comfortable, so enjoy the sled.
