dr is happier. i've geared my xr down (14 tooth CS) to work optimally off road so that has an affect on road. still gets me down the hiway just fine, just not as fast or comfy as the dr.
as for the tank i'd say go with a clear ims if you need maximum fuel but i would not go any larger. any more and you're carrying too much weight up too high. a 200 mile day of single track would be mega epic and there are places in the ark valley/taylor park to plan and peel off for gas if need be. you're proabably think longer rides out to the advanced stuff in taylor park aren't you? just gas up at the taylor park store.
like i said you can throw 2 large msr bottles with gas in a pack if need be or get a rear rack and strap a gallon on the back or mount a small koplin tank on the rear.
