Hey Dino, maybe you're putting the vest on wrong?

LOL!!

With grips, the tops of your hands will still be cold without heated gloves.
This one's easy, nobody ever told you the secret? When using heated grips, to keep the rest of your hand warm,
wear sport racing gloves (gauntlets).You see, sport racing gloves, like AGV, Teknic, etc, have single layer palms for excellent control feel but padded and armored backs for protection. The thing that works for sport also works for heat: the thin palms transmit the warmth and the thick backs keep it in.
Same with seat, still need a jacket liner, the liner instead the vest allows you to plug in your gloves into the ends of the liner sleeves. If $$ is no object, get it all. but make sure with all that stuff you don't overload the bikes electrical system.
Oh, our bikes don't need to worry about power. Valkyries have the full Goldwing electrical system, a 1200 watt alternator, but none of the stock doodads that actually draw that amount of power. With no electric reverse, no radio or CB, no cruise control and other things, we have power to spare!
