I heard about a base grind theory that made a lot of sense, but mostly to racers. It involved getting 3 base grinds over the course of the year from a facility that is able to greatly vary the type of texture put in the base. One at the beginning of the season, when the snow is wet. This basegrind would be a fairly deep, textured grind. The theory behind this is that when there is very little air in the snow (lots of moisture), you want more air, or a bigger cushion of air in your base. Towards the middle of the season you would want a less deeply textured base when the snow is very cold and full of air/less moisture. Then the most textured base in the spring when the snow is it's moistest and slushyest. This could be very costly and probably not necessary for 95% of riders. My thinking is maybe two grinds a season and just have the same, more textured base for both spring and early winter with a good storage wax over the summer. I know there is a very good base grind shop in tremblant, quebec with a fully automated stone prep machine that you can just punch some conditions into and it will adjust the stone for it. I.e. moist snow, cold snow, dry snow, sticky snow etc. Their staff is also top notch.
