rope/cord diameters?

[broadsword]

this has probably been asked a thousand times so apologies if its getting abit stale but for my benefit, what rope and friction cord combinations are you climbing on and what diameters are you all using? im on blaze and 10ml ocean poly. slips if not setup right but when fine tuned glides beautifully and locks down tight.

any takers?

13mm xtc / 8mm ocean VT/Hitchclimber

grips on its own 9+ times out of ten

I don't think there is a set way of doing it, ie you can't just say 11mm rope goes with 8mm hitch cord 12/9 and 13/10 etc. althought that is a good start IMO.

 

It depends on the flexibility of the cord, the higher the flexibility the higher the diameter of the cord can be compared to the rope, but it also depends on the knot as well. with a blakes hitch you would use like for like.

 

There are so many variables. Blaze and the smaller diameter OP cord go well with a vt set up though.
