I got mine yesterday and used Renegades in the front (didn't have time to adjust the wire to make the new front Vipers smaller) and vipers in the back on a 19 mile endurance practice today. Love them!
No twisting and my girl gaited more than usual...won't gait in boas and I had four pair of boas break in 3 weeks!
I'm exchanging the renegades but tried them now for over 60 miles in last 2 weeks. Only one flew off in a gallop and one twisted first ride...still way better track record than boa!
