I've got a 7300FX Disc that I ride all the time. I'd stay away from the discs (unless they've got to something better than the Hayes MX2) which are a PITA to keep/get properly adjusted. The '07 has Shimano discs, so they're probably a little different.

Overall, it's a tough bike. Not light by any means, but durable. I'd also suggest getting narrower tires (I ride 28 Gatorskins @ 120psi) than the 70psi Bontragers that come with the bike.
