I bought new skis late this season and the Prophet 98 and the Bonafides were both among my finalists. I demoed them both in varied conditions and found that for my liking, the Prophets were more versatile. The Bonafides have got a ton of press and before my demo I thought I'd buy them. I found them greeat in wide open spaces--groomers, crud, and knee deep powder. They're quick, stable, and have no speed limit for mere mortals. However, the Bones were a lot of work in anything that even looked like bumps. They were equally challenging in tight trees. Admitedly, the Bones that I skied were the 187cm length and I probably would have liked them better in a shorter 180 cm length.
The prophets on the other hand had much the same performance, but for me are a lot more fun in bumps and tight spaces. With either ski you better be prepared to ski with good technique and energy. They are drivers' skis, not meant for posers. I bought the Prophets and have really enjoyed them. I'm very glad that I demoed the Bonafides because if I had bought them without trying them, I would definitely have been disappointed the first time I tried skiing any sort of bumps. Just my opinion. It really is a matter of personal taste and I'd recommend that you demo before buying any high performance ski.
