I just installed the new pro-x series fat sacs and the quality is much better than a regular sac. they cost more but it's well worth it. They are thicker and have better fittings for filling.
Barefoot International PRO-X Series 1 fat sack with the new Tsunami Pump right around $250. 750LBS Awesome package and very very durable The new pumps FILLS FAST
I just got a free one. Brand new, 540 lbs, coverless Launch Pad. Of all the sacs I have the free one is definately the one I'm the most stoked on!! Let's see here, 540+560+350+350=1800 in the little ProStar 205. Hmmmm yes I think we'll be alright.
