Geko are just out of the bleeding edge phase – might be worth waiting another season to see how the new version works out.
Mohair or nylon is the big choice. Mohair glide better, nylon wears better. Most of my friends have G3 which has an excellent attachment system. I’ve got Montana – seems to work fine.
Make sure one in the party carries a bar of wax in case things get warm and wet!
