The Sherlock looks good although isn't it directional, or am I reading an older model review. The shape looks very similar to the antler.
The Sherlock has a more pronounced rocker in the middle, antler has similar profile but more moderate, this is supposed to make it less squirrelly on the flats. I was told that the antler is the next iteration of the X8
I've heard that t.rice is a stiffer version of trs. So trs won't give you the massive stability wherever you go, but once it's broken in, it'll be soft enough to butter and jib but stiff enough to hit the groomers.
OP...you really also need to name your mountain for the "best all mountain board"....
the best all mountain board for La Crescent Iowa will be different than whistler and different for utah.
I suggest a bit of observation and inquiry at the mtn that you ride at.....only observe and interview the local core riders...not the gapers. I'm sure that you will discover there is a common theme. Riders' styles and skill are a product of the mountain...therefore certain designs will take advantage of the mountain.
Those Prior boards are sexy! Pricey, though. Will have to demo next time I'm at Whistler.
I demoed the Prior AMF last year at Whistler.
Very solid, stable board. But there's nothing special about it versus mass produced boards from other companies.
Make sure you ask them to sharpen the edges before you go. I found the edge hold lacking.
I also demoed the LT Dark Series and Travis Rice Pro the same week.
I bought the Travis Rice. Very solid and stable but easier to maneuver than the AMF imo.
