> Hi. Thanks for your help. Have seen these. Seem great but wondered_-: I think the tying on loop is too high to introduce someone to belaying from it.
It's fine to belay from. The only caveat with the belay loop is that it sits horizontally rather than vertically. This means you need to orientate the belay device, left or right, so that it works with whichever hand is dominant.
> Also if someone wants to use a climbing wall and pass the wall intro test, they normally have to tie on a figure of eight, then thread it through the legs and waist and back thro the figure of eight. Would it be acceptable to tie just onto the high loop using figure of eight at a wall?
Yes just tie on to the belay loop as normal. It's not just DMM that makes this style of harness, Petzl, Edelweiss, Beal etc have made harnesses of this type. It really shouldn't be a problem.
> Is there a more conventional harness that does wide range of fit?
The DMM Brenin is nearly as versatile.
You're welcome.
