In reply to Rob Stratton:
Personally I've found that the trigger is quite nice on mixed ground as it makes the axes feel more precise when they are in all sorts of torquing/hooking positions, but as above they can sometimes feel like they are in the way on steep ice and I did think it was slightly more comfortable when I took them off. Since I fiddled with them the triggers have stayed on permanently though as I could have switched them in and out depending on what I was planning to climb but to me it makes too little difference to be worth the faff.
When I first got my axes I experimented with moving the trigrests up the shaft, just because I could, and decided that there was no real benefit. It's also nice to be able to go straight from daggering to a more conventional swing without having to stop and alter your axes all the time. Moving them up or down a notch is something I have occasionally done to accommodate different glove sizes mid-route but I usually leave them set to the correct size for the thinnish gloves I lead in, and then when wearing thicker gloves there is plenty of room to squish the extra material in to, which does not feel uncomfortable or cumbersome.
So the fact I don't move my triggers around means I have taped all the way down to the top of the orange plastic in the handle and is great like that. I also added some electrical tape to sort of 'seal the end' to stop the grip tape getting caught and peeling off upwards and that worked well, and stayed stuck on for a few seasons which was longer than I expected!
