If you are
really sure you are going to be getting into it, a splitboard is far better than snowshoes. It's also far more expensive. Snowshoes are not bad and sort of have their place in your arsenal. If you are going the snowshoe route, maybe see if you can find a pair of
Verts. Spark is selling them with splitboard pucks to attach their bindings to them this season, but that won't work for you. See if you can find them with the strap configuration. I suspect they will still sell them directly from the site. Verts are great for climbing, especially very steep stuff. Work adequately in most conditions. Going downhill they are kinda lame though. They are usually around $70 though. I'll use them in the spring for climbing steep couloirs when skinning is too much work or just not an option, so they are worth having.
