My wife uses a Gerbing set up (G4 12v -Glove with jacket liner) that she originally used just for motorcycling, but has used them when it is going to be -10F or colder on her sled.
Most of the time, both us us are good with just the Ski Doo rigid gauntlets and grip heaters, in all but the coldest conditions.
We average 150-250 mile days very often.
You can use the G4 glove with a Y-Harness, instead of with the liner. It is a little less hassle plugging the gloves into liner sleeves vs. the Y-harness.
You have to deal with plugging into the sled, but never worry about running out of battery power. Depending on your typical day on the trails would likely determine the direction to go. Most sleds don't have much excess amps to play with, but with her 900 Ace 4-stroke Blizzard, she gets by with it, without stressing out the charging coils to much. You just need to keep the liner heat to a minimum and adjust the gloves as needed.
