@vagabunda79 - I don't think theAura and SOS feel similar at all, but I still think you'd like the SOS. I really have to "eeney, meeney, miney, mo" about taking out the SOS or the Kikus. I highly recommend you pull the trigger on the SOS if they're not sold out - and don't be afraid to go long if you can (especially if you've been skiing Goats).
The Abyss, though, I'm still not sold on. I've read a couple of times that they have a "break-in" period before they feel really great, and with my knees giving me problems this year, I just haven't spent any time on them. Also, I may have had them mounted too far back at 2.5 cm. With my Shiros being so fun and easy, I have a real hard time taking the Abyss out instead.
