I tend to have very sweaty palms/fingers when I play, especially in high-stress situations so this idea is actually very intriguing. I am curious however in regards to the weight it adds to the bow and how it affects the balance- I have surgical rubber tubing that goes over the gap between the leather rest and the frog (to protect the thumb) and that has boosted the bow weight to 85.3 grams. I'd like to try something similar to the stringvision grip but something that only covers the front and back of the frog only (to minimize weight).
