sleeve bag vs. convoluted bag

[texastrendz]

i am just wondering what one advantage has over the other. i have to trucks with off the axle setups now and they both perform great. i was just wandering how they would perform with a sleeve style bag. my dually project has the bags on the inside of the frame because of the narrowed axle and dual tires in the rear. my new project is single wheel with the bags in front of the axle inside the frame. any advantage of a sleeve bag? any help would be great thanks. daniel.
