People get in trouble when they get fingers caught in dive loops, etc. And any handle that's going to save your life you should have a solid grip on it, not a finger tip catch. I think tackified is uneccessary to maybe hazardous. IMHO.
Home Depot sells a pair of gloves by Firm Grip called the FG Extrema. These are not ordinary work gloves. The gloves are all black. The fingers and palms are a tacky, thin leather. The backs of the hands are spandex. There is a velcro tab at the wrist. I paid $12 for them and plan to jump with them this winter. I tried on different kinds of similar gloves at two different stores and wore different sizes across the board. It was easy to go into Home Depot, be able to try on the gloves and know they fit perfectly. If you are thinking about buying the Neumann? gloves I think you will be happy if you find a pair of these gloves.
