Stop sweating the disc thing. They do add a wee bit of weight - but they are worth every GRAM. Virtually everyone that I've ever talked to absolutely loves the control and power of their discs.
A good friend of mine's been MTB'ing for 10 years...he's been such a slow convert to anything new. He finally upgrade to discs (along with a new Titus Switchblade)...he just goes nuts ranting and raving about "how come I waited so long to go with disc brakes?"!
