Re posted from a previous similar thread:
I recently bought the burton wheelie board case, very good construction quality, good gear protection, nice boot and clothing removal bags, plenty of room. In the 166 i can easily fit 2 boards and all the clothing ill need for a 2 week trip. I only take this one bag as my check in luggage on snow trips. Empty weight was about 3.5kg. Highly recommended. I managed to squeeze 2 sets of boards bindings and boots plus clothing totaling 30kg for the current trip to Japan for a whole season. So there is plenty of space.
The gig wheelie is a lot simpler without the additional nice features that the wheelie board case has.
The locker wheelie is just massive and heavy (~7kg empty weight), nice additional features but i dont think its worth the extra $ and weight.
