I used to use a Stihl 011 for climbing until it just plain wore out. For the last 15 years or so I have been using Husky 460's. I have only had some pretty straight removals for the last few years so the 460 seemed fine. Two weeks ago had to do a bunch of limbing on some large live oak. The 460's are too big for that. I climbed with them anyway, but became so tired at the end of the day that I was going to get sick. My age might have some thing to restrict me. Thanks
