Not to add more fuel to the fire...

3 degree base bevel is probably fine for twisters, pivoters and tail sliders. otherwise, it is that un-nerving!
...here's an interesting twist. Before the Beaver Creek WC races in November, there are usually a ton of RMD races that the WC stars run just to get in gate time and race starts. One is usually the Nature Valley (or whoever is currently sponsoring it...) races at Loveland, usually slaloms. A couple of years back, there was a lot of new, soft snow before the races, so they watered the hill...with wayyyyy too much water. I talked to some of the gatekeepers and course workers, who said it was suicide to be on the course unless you were on skis or wearing crampons. I also heard that *some* of the Euros were going with a...get this...4 degree base bevel, and 7 degree side bevel. If you take out three degrees from each angle, you get back to 1/3. So a 4/7 is like a 1/3 tilted wayyyy over. So why would anybody do this? The theory is that guys were experimenting with trying to have the body go as straight as possible, and just swing the feet wayyyy out to the side to just get enough lateral to make the gate...and also to get a massive edge angle. So that's the 4 degree base bevel part of the equation. The 7 degree side is so that once you get way out there, you have a knife edge that'll hold at the extreme angles you'll be committing to.
Is this something I'd do? Not on your life, for all the reasons that everyone has noted about extreme base bevels. One pair of my Head IGSs last season, unbeknownst to me, actually went to a 3 degree base bevel, and the first day I found that
out was running full length, high speed GS on rock hard course-prepped snow. Scariest thing I ever did on skis. So, to sum up, I'd stay the hell away from anything bigger than a 1 degree base bevel unless you really know what's going on. But if you go big on the base...well, I think you've got to go big on the side, too...or stay home...or take up bowling....
