I tried to keep one glove on while throwing but found I need the feeling of Both hands to get everything just right. I use my left hand to insure my angle of release, both in driving and putting.
It just holds the disc for awhile before I release, and I can feel what the angle is better with 2 hands than one...!
i try not to use gloves, i really like to have a good feel of the disc. But here in michigan its gets really cold. so i bought a pair of gloves(mittens), the fingers unsnap and snap back onto the hand. there very convienent and keep my hands warm. good luck and have a great season!
