quoting Cory: "Crazy question: If you had a Wraptor, would there be any reason to bother with a Haas system? Maybe for shorter ascents? Lighter to pack around?"
Having a Wraptor makes me more reluctant to purchase a HAAS system. I do just fine with a frog walker when needed. Forgot to put the Wraptor back in the truck and did just fine with 3 ascents of 75 feet in a black oak. Well one was up a pine to get into a part of the black oak
My asthma is acting up, so I missed the Wraptor today... Just took it a step at a time and got the job done.
My rope walker (variant on Porkbrick's) is like the HAAS, just more compact and cheaper, and maybe, guessing here with a bit of pulling numbers out of my ear, 85% as efficient, maybe way more, can't feel like its way less. I've never held a HAAS. If you don't have an ascender for the floater, 50-60 bucks on ebay.
I have demo'd a Wraptor for residential, and got SPs to buy one. I would definitely still want a rope walker for climber longevity. Start adding up 20' here of pulling on the rope with your hands, especially 1:1, and 30' there, plus when things are easier, you tend to do them the better way or more predictable way, giving you a safety margin.
Stephan, do you wish you were hands free of the ascender in your trees much? That double ascender seems like it would be bulky.
I haven't touched a handle ascender in a while, all rope walker.
