I don't share tokyo's view on burton ratchets, but the main thing is to buy from a shop with a good return policy. That way if you buy and try, and they're just not working for you, you can go in and swap them.
And that there is the truth. Havent heard of service like that from shops in Japan, but it would be saving me a lot of pain right now if i could just swap out my boots/bindings.
No more buying bindings online for me.
