Buckingham Titanium Climbers ATM F887 with Big Buck Pads 3202C.  I've used these a half dozen times and the rest time the time they've been riding in my truck for rescue purposes.  I've posted lots of pics so you can see there's almost no wear.  I bought these about 10 years ago when I was scheduled for a total knee replacement.  I wanted the lighter weight and I wanted pole gaffs because the thought of having tree gaffs stuck and while trying to "unstick" them, pull my new knee out of the bone just creeped me out. Anyhow, it didn't happen and while recovering  in the hospital I bought a tracked lift and found I didn't need to climb anymore.
