Anybody have the Mammut Crag Sender 8.7mm (not the Alpine Sender) and can comment on using it for regular sport - whips, project working, dogging, etc.?  How quickly does it wear?  Any grigri slippage for folks that aren't the best or just use the thumb press, thumb release lazy method?  Thanks in advance for any input.

Not completely sure if this applies cross-brand, but the only hyper-skinny rope I’ve used was the Beal Opera 8.5mm and I hated it. Couldn’t imagine using it for projecting, the stretch was unreal. Working sequences would be obnoxious, you’d constantly be sinking below the spot you’re trying to work. I only used it for a handful of pitches (it was my climbing partner’s) so I can’t comment on longevity

I’ve owned a number of Mammut Ropes across all the sizes.
my two favorites are the 9.5 crag sender for “daily driving” projecting sport climbs, toproping, etc and the 8.0 alpine sender double/twin ropes for big routes and more difficult trad climbs

They’re all super durable and have treated me well

IMO Mammut ropes are very stretchy compared to other ropes in the size range. The 9.5 still stretches a bit even after a hard take to work a move or sequence. However, it’s been super durable and is very supple too.

Sterling ropes are also great and seem to be a bit less stretchy overall. Atleast in my experience. Also extremely durable 

I’d recommend going thicker for what you’re mostly doing

Edelrid 8.9 protect pro deserves your consideration. Beast of a rope and tiny.

The Mammut Crag 8.7 is definitely not a good workhorse rope from my experience. I workhorsed one for a week in Smith because it got packed by accident and it felt like it reduced its life by half. If I were committed to the Mammut Crag, I’d go to a thicker diameter.

The Edelrid Protect 8.9 got mentioned above, I love that as a workhorse.

Thanks all - this is super helpful.  I bought it on a whim because I saw it for cheap and was blown away that such a thing existed.  I'll definitely heed your advice.  Also, will echo the Mammut 9.5s.  They've been my go-to and have lasted a long time.

Cheers everybody - stay safe out there.

Haven't even opened it.  Given the reviews and comments found online - everybody's scared me.  I'll probably just use it as a gym cord...
