i have a 163cm Never Summer Legacy board that I split last season. It's in good shape, and I could sell the board, with the full voile kit for $200. The board is just too short for me. I need big boards. I would agree that a factory split is the best way to go, and these days the used selections are pretty good. However, a DIY split is the cheapest way to get into it, and they work just fine. My main splitboarding friend has been doing it since the beginning and he has never owned a factory split board. Every couple seasons he buys a new resort board, and splits his old board. I can't convince him that a factory split is worth the expense.
and i would never do those approach skis. the whole point is to get the gear off your back. i see no point in having approach skis and a rigid snowbard. too much gear. sorry, no offense to the guy that likes them. i just don't get it. Also, many back country areas require long approaches on a trail, and snowboarding back to the car may not be possible. When that happens, I just switch to ski mode and leave the skins off and ski to the car. It took awhile to get the hang of it, but now I am comfortable skiing my splitboard down a trail, traversing, and skating the flat sections.
Splitting is the way to go if you are a dedicated snowboarder, and once you get the hang of the transition, you will be fast. I can switch out as fast as most AT skiers after a few seasons of practice. Tele skiers don't even take their skis off at the top, so they've got me beat. and the really fast AT skiers are hard to keep up with too. If you go with Skiers, make sure they are stoners, so you can transition while they are "medicating".
And check out the Karakoram binding and clip system. It's pretty superior and much quicker than the voile based system. It's more expensive, but I think it's worth it. I'm saving up. Karakoram | Innovate. Ride. Explore.
