I never noticed there wasn't any heat for the palms, I guess that say's it's not a big deal because my hands stay warm. I don't know if I would bother with adding heated grips, a non issue so far.
As far as to what order you put the gloves on I just eliminated the small grommet and pulled the coax connector back out so now I put the gloves on last and pull both cuffs over the jacket. Maybe if it rains that's not the best solution but with both cuffs pulled tight I can't see too much water getting back into the inside of the gloves.
So far I'm happy with the Synergy 2 jacket and gloves.
