Compatibility of Ascenders and Rope Wrench with 13mm Rope?

[Treespasser]

Hi all,

 

I'm wondering about the compatibility of foot ascenders with 13mm rope instead of thinner rope.

I know using a thinner rope, say 11.7mm, will run a lot smoother.

I'm just thinking about whether it's worth spending £150 on a new thinner rope, or just getting by on my 13mm with the normal foot and knee ascenders.

Also how does the Rope Wrench handle 13mm?

(By the way I climb DRT and highly considering the switch to SRT)

 

Many thanks,

 

Jack

I'm on 13mm dDRT and the Harken Ninja and HAAS both work just fine.
