I had a years worth of time in the saddle on the morphine. It was a very nice, burly, versitile frame. I had it set up with a sherman, boxxer, and a monster t, in each case it served its purpose very well.
Now i'm currently on a Sinister Ridge, which is very pimp. It has a 1.5 headtube so you have the option to run the bigger sherman SCs. Handwelded here in new england, i'm impressed with the bike so far. I have it set up for xc and light freeride, its a killer trail bike, freeride bike, and it felt good on the DJs too. I havent had a chance to ride it DH so i cant give you any input on how it performs there, im sure it is amazing there as well.
If your not going to be pedaling around the imp for any lengthy ammount of time, or on the trails, then you'll probably like it. I tend to like a more do it all bike, which includes trail friend, and the imperial was far from at home on the trails IMO. They are nice for dj/park/dh/fr tho.
Heres a pic of my ridge for you to drool over
