I was under the impression that the red and fiber were the exact same ski, with the red being the left overs from a piss poor 2004-2005 sales season. I definitely could be wrong, but I have skied both and I didn't notice any difference. I own a pair of older Atomic R:Ex, have skied Rossi B3's, Volkl Ac4, Volkl Karma, k2 public enemy, k2 apache recon and I would have to say that the Legend 8000 is probably the best out of the bunch if you're looking for a midfat that is decent in the bumps. If you get them, you won't be disapointed. A 178 is probably the way to go, but if you spend more than 50% of the time on the groomers than I would feel comfortable recommending a 170, even with you being 6'1". I thought the 8000 was very easy to ski, more so than the others I tested and they were extremely stable. They were quick into the turn, but not out of the turn and had a nice damp feel that seems pretty typical of Dynastars.
As far as boots go, I would say go with either the 100 FR, or 120 FR. Just be honest with yourself and determine what kind of skiing you will be doing the most. If you're a hard charger, go with the 120s. The Tecnica Diablo Flame falls somewhere between the 100 and 120, and is now sold as the Diablo Magnesium. I own a pair of the magnesiums and they quite simply are the best pair of boots I've ever used. BUT that's because they fit my feet. I can't recommend one boot over the other because it all comes down to fit. If your foot is narrow, then you are a canidate for Lange. Just go into a shop to get sized up though, even if you don't want to buy from them.
