Nice SmaCk on the newbie. I may not be fast but I'd probably be ahead of you.
I live in Northwestern Montana (which for those that don't know has a lot of hills). I haven't yet been in a situation where my V-brakes (Avids on Ceramic Rims) didn't do the job. My statement about attained speeds was in reference to dowhillers. I suppose if I pointed the Rig down Dave's Dive on Big Mountain I would want disks but then the speeds would be approaching 60 mph. Speeds less than 40 have never been a problem with my V brakes.
I'm not a total weight weenie but Avid BB5's and the bontrager hubs outweigh a non disk hub and Vbrakes by quite a bit. As well as cost more. So far, the Avids haven't been awe inspiring. maybe a high end hydraulic like the hope mono minis' would change my mind. Also, I have been in mud races where disks had as many or more problems as V-brakes.
My real complaint with the eccentric is the 'wedge' system used to anchor it. In design it is similar to the threaded headset that had a 'goose neck' or 'quill' stem that was anchored by a wedge. To remove the stem you loosened the bolt and tapped on it. the wedge came loose and the stem came out.
the EBB on the rig doesn't come apart so easy. In order to keep it from slipping under pedalling effort, I have it tightened down so much that I need a hammer to knock it loose. Like I really wanna carry a hammer with me on a bike ride.
The EBB that came with a friends Salsa has a much better system for releasing the wedge.
Anyway, I'm sure I posted stuff that is common knowledge (or should be). However, I still stand by my preference for quality rim brakes (and yes they do exist) with a quality EBB over low end Disks and a crap EBB just cuz it's fashionable to have disks on a bike.
+++++++++++++
I thought some of you might find the following humorous. I am posting below an email conversation I had with Fisher bikes. Talk about CYA. Salsa is more than willing to post information about their EBB. Since it is email, the initial request is last.

Unfortunately I don't have a diagram for this. Liability reasons stop us from providing this, because if a consumer does this wrong and causes damage to the bike or them, we're held responsible, this is why I refered you to the dealer.

Thanks again for directing me to a dealer.
I fixed the problem myself last night. Q.E.D. I would have preferred
some sort of diagram from Fisher. But probably for legal reasons you
guys are afraid to let the bicycle owner think on their own. What if the
BB had slipped and I was 10 miles from the trail head? How is my dealer
going to help me then? Isn't mountain biking also about being self
reliant? A responsible / safe rider should be able to work on the bike
themselves. And Fisher Bikes ought to help promote safe / responsible
riding by enabling the cyclist to educate him/her self.
I did found a real nice diagram showing an eccentric BB on the Salsa
site.
Too bad the fisher site isn't more helpful.
Finally, I figure that if the dealer couldn't set it up correctly the
first time they won't get it right the second time.
Regards,

This does happen sometimes, I would recommend sourcing any trek or
fisher dealer to have them adjust this properly.

Thanks for the quick reply
I did loosen the screw (first I backed off the locking screw) then I
loosened the hex head cap screw. The BB would not budge. The bike has
about 30miles on it since new a week ago. My fisher dealer is about
2250miles away.
My guess is it slipped while riding (just too powerful I guess) and it
is now jammed. Chain stretch on the park chain checker is at 25%.
Thanks,

Thanks for writing
All adjustments are made at the bottom bracket, you'll loosen the
eccentic BB, turn it forward to tighten the chain and retighten. I would
highly recommend having your fisher dealer perform this.

I need to adjust the chain tension. My bike dd not come with any

find anything on the web site.

eccentric BB installed in the Rig.
thanks,
