I have the FirstGear... tried the Tourmaster... the TM's were real bulky... the FS are not that bulky, and work pretty well. I didn't like having to buy the controller, as an extra cost, for the FG's... so I just plug them into my TM jacket liner and run them off of that (call me cheap).
I got a pair of the TM gloves real cheap, tried them, but man were they bulky... and bothered my fingers... something inside, the lining. The plastic housing that held the controller was all messed up, came from the factory that way, so I returned them.
I guess I'll just keep using the FG's untill I see something that looks less bulky and comes with the controller... cheap!
I had heated grips on the Wing... nice, but not as nice as heated gloves. The heated grips will not keep the tops of your hands warm, or your thumbs. I do have some real nice winter gloves, and even with the heated grips, could not keep my hands warm in the low 20's upper teens for long rides.
