Hello,
I would say one of the major factors in buying an 80m rope is weight.
I've used a few DMM rope, the Galaxy and Revelation.
DMM rope are really nice to handed but durability is not great.
Galaxy is stiff but last forever but is not very light and on a 35m sport route you are going to notice it.
I'm using a revelation at the moment more supple than the Galaxy and stiffer then the DMM ropes. Lasting quite a while and not too heavy.
I'm also using a Beal Diablo (9.8mm) for working routes, and RP on a mammut serenity (8.9mm) which is dying extremely fast.
I would look at ropes from 9.4mm to 9.6mm as a good compromise.
Hope this helps,
Chi
