"it feels like you're pulling less weight".
That's one of the big reasons that I like the glove style releases so much better than the wrist strap style. The weight of the bow is spread out over your entire hand instead of being concentrated behind your thumb and your pinkey finger.
I don't necessarily feel like I am pulling less weight as far as my arms and back muscles are concerned but the weight that my hand is holding is much more evenly distributed and much more comfortable to hold at full draw.
