I would contact some teams that have used bevel gears and see what they think. Chief Delphi I think used a four wheel drive with bevel gears way before we did. You might have to reach way back for some advice there. Martus, Eaubry or Johnson may remember, it was long ago, maybe '98.
If you are going to nationals, take a camera and a notepad and go around the pits asking and shooting. Soap may be able to give you a list from the their database of who might have crab this year. We did not do crab this year, I think that was a good decision the way the field and game are layed out. Next year who knows. Our 2003 Championship robot used crab and a descending foot and it was just right for that game. What I consider the best way to get from here to there in a straight line.
For a bit of trivia, crab steering is what is used for studio camera pedastels in television. They have known for many years, that it is the best way to get a shot when you aren't handheld.
