The Switchblade Iceblade is one of those things that I wish I had purchased as soon as I started snowkiting. Like the trainer kite which I purchased to share with my friends and family; only after I struggled with a full sized foil during my own lessons. Or the light-wind Splenne that I purchased a year after I struggled with a typical kiteboard. The Switchblade may seem expensive as first thought, but it is so worth it!
There's a reason why you never see a Switchblade Iceblade for sale on the used market, people love them and they last forever.
Not only will a Switchblade extend your winter kiting season in the early part of the winter, before the snow has fallen...but it will also extend your snowkiting season into the Spring as the snow dwindles on land, but the lakes remain solid! But most surprisingly to me, it has proven to be a great asset every time I have stepped onto a lake this winter! Sure, the snow may be bonded to the ice in some places, but it's rarely bonded thoughout the entire riding area....and generally it's spotty throughout. This is why I love my Swithblade! It makes every lake a blast to ride. Faster, safer, and just way more fun! It has completely saved, or greatly improved everyday I've ridden the lakes this year!
I think 2 inches is way more than you need. I have my Switchblade max out in the depth setting and it's about 1/2" below the bottom of the board. The snowblade cuts through the snow when edging, so you don't need to go that deep. When the board is edging is snow you don't need the assistance of your blade. If the snow isn't bonded to the ice, your board will cut right through. My switch blade is adjustable in and out, as well as up and down. Avoid all the trial and error, metal work, and hassle. Purchase a Switchblade. You won't regret it!
I have two snowboards. An old short one for the switchblade and a better longer one for regular terrian and the hills. But I would not be afraid to mount my switchblade to my good board and simply take the switchblade on and off when kiting on the lakes. However, I'd leave the bracket attached as it goes through the wood core...and just simply remove only the blade.
FYI, the blade should be inline with the outer most edges of your snowboard depending on the sidecut of your board. I also just checkout my switchblade and noticed that I'm not all the way down on my depth setting. I'm actually about in the middle of the 1'' allowed of travel....which gives me about a 1/4" below the board. Max would be about 3/4". All the way up would be about -1/4".
The Switchblade is pretty thick. You may find that the hockey blade can't handle that much side load.
I agree, as long as I'm on any lake I always use my Switchblade. But if I was to go kite the mountains, a farm field, or some park area I use my regular snowboard. No reason to dull my Switchblade on some dirt, grass, and/or rocks.
