The point is.......
It works with "any" size paint.
You get 8 aluminium tubes in different sizes.
You can also get shorter/longer front's for it.
I don't know if it will go on the spyder though.
Its nothing like the boomstick( I wish i could trask the boomstick but i cant, hell of a good barrel) but you have to buy 3-4 to always have the right size (my opinion)
Hope that helps.
