I have the Float RLC 150 on my Mach 5 and it's a great fork. I do have to concentrate a bit on the steeper climbs to keep the fork down but it's not enough to make me want to change forks. It's been a great fork so far. Stiffness with the 15mm axle is good, definitely better than a regular QR, but not as stiff as the 36s on my FB, obviously. If you do decide that the extra 10mm is too much travel the fork comes with a spacer to set it back to 140mm, but i don't think it reduces the AC measurement.
I have tried a 70mm stem and a 90mm stem and they made a significant difference to climbing. The 70mm stem was way too short and the front end wandered all over the place. The 90mm stem makes everything, even descending and technical stuff, heaps more comfortable.
So, yes, i'd go for a 150mm fork. The TALAS might be a good option but i'm not a fiddler when i'm riding so i wouldn't use the adjustment anyhow. If the Revelation has a shorter AC measurement i'd give it a try. I did consider that fork but was swayed by a great deal on the XT wheelset that the LBS gave me and it only had a 15mm hub, not a 20mm hub.
