This one would rock, as if you look at the unit on the bike, it's the Snowtrooper backpack. Do as said above with the new tool Scout backpack with hoses that connect to a Snowtrooper backpack that fits onto the; and here is the deal maker or breaker the Saga version of the Speederbike
. That is about the best version they have even know it's still too big and the steering vains are all wronge, but it has the better control arms and looks much cooler than the POTF2 version. That is if they are going the cheap route.
As others have said though it would be awesome for a new tool Speederbike, as they are my favorite, but I don't see that happening anytime soon.
