Jim, currently and for years I've used the Truball Copperhead. I really like it and I've been very successful with it. The Velcro on the strap is wearing out finally and although a buckle strap is better, I was fine with it til now. I'm looking for a new strap for it but in the meanwhile,
I just ordered a Scott Wildcat with the buckle strap and strap to the head. It's one of the very best IMO.
