HAAS ascender with kong duck, ct rollnlock, ropeman2

[Arrozdoce]

Hello

I'm looking to get one of these devices for a new rock climbing setup but it would be a great bonus if it could be also useful doing treeclimb.

Right now I have a foot ascender for drt/srt soo I was thinking, would any of these or similar devices (kong duck, wildcountry ropeman 2, ct rollnlock) work reliably well in a HAAS configuration? (bungee cord and a footloop)

Which one could be more useful in arb work?

 

Thanks in advance.

How u doin mate,hope alls well in sunny portugal.

I use a petzl croll chest ascender with a footloop.

You could use any type of ascender but i personally avoid any with sharp teeth like the kong duck,might have a detremental effect on your rope long term
