I am not Pro at tree climbing or claim too know much about climbing gear but that saddle looks like too "gadgety" for me. I know it was designed by great champion climbers with a heck of a lot of experience but it looks to me like it has too many little belts and whistles that a regular joe climber will probably not use much.
Just me being another ignorant opinionated e-poster I guess!
Let the fire storm begin now
Ekka, I like that one:
"you'd need lots of places to hang say drills, spanners, beers and smokes! "
