I've been happy with my Bluewater Excellence 8.5s. They've worn well and handle well.
I climbed on a partner's pair of PMI Fusion 8.6s at Redrocks a couple of years ago and liked them, too. Thought they handled perhaps not quite as well as the BWs, but so close as to be a matter of taste only. I did notice that the two strands were two or three meters different in length (ropes were newly purchased; not cut) - a moderate annoyance when flaking over an anchor leash to bring up a partner. Haven't heard how they've worn in the ensuing years.
As a matter of interest, you can still find Fusions listed at Mountaingear, etc., but a visit to the PMI website just showed me that they've changed their double's model name to "Synergy" and sell it in two diameters, 8.1 and 8.6, either dry or regular (apparently replacing the old Verglass and Fusion). Both diameters are now UIAA rated as both doubles and twins, which used to be true of the Verglass only and is kinda nice. Only ropes on the market with that distinction, I think. Don't yet see Synergy listed on any of the on-line retailer pages.
My partner for my upcoming Oz trip is also in the market for doubles, and I think he's going for either the Mammut Genesis or the BW Excellence. He's climbed on my BWs on two prior trips, so apparently he didn't hate them...Edited to add: Appears I was wrong about the PMIs being the only ones certified as both doubles and twins.
