Rope for what use?
I've used predator, tethrd ropes, 9mm htp, amsteel bridge.
The splices on the tethrd ropes are nice, but the rope is my least favourite. Predator handles well but kinda bulky. Htp is nice, recommended by a ton of people here, great for rappel, srt with safeguard/petzl hand ascender. Can't splice - knots or tied loops only.
Oplux looks interesting but $$.
I only consider ropes from reputable brands, and search for suggestions here. My preference is for a small diameter lightweight rope that handles well and is tough enough to resist damage. Also for SRT low stretch.
