with straps you don't have to grip the poles as hard. thusly, when you are tired, it's a better way to go.
only the four fingers go thru the strap, not the thumb ... this is a safety issue. it makes is vastly easier to disconnect when a pole gets jammed and you keep going.
i prefer the angled grips, and the more angle, the better.
once you get to pacer poles, the strap inverts and works differently, and you don't have to grip hardly At All.
peter will be bringing his carbon pacer poles to the GGG, for if anybody wants to play with them.
