I've been using Safety Blue for about 5 years. Soft feel, the second-strongest climbing rope on the market (7,700 lbs) and it's about the least expensive rope you can buy. The high load rating is good for me because I downgrade my lifeline to a handline when my old handline wears out. This way I'm always climbing on the newest rope. Plain white with blue core. Virtually no milking.
My next rope is going to be the Blue Streak. 8,100 lb rating, has a stiffer feel- reminds me of the old Arbor Plex, but not as bad. When I tried a new line Saturday it didn't seem to snag with ascenders as easily as the Safety Blue. A little more money, but will make it easier identifying my lifeline from the handline. Blue and White striped. I've heard this rope needs no milking.
