Slam specialties re6 compared to Firestone, ECT

I'm looking into purchasing new bags for my mazda. How much more lift does S.S. re6 give compared to its competitors? And what are other benefits to these bags?

i just bought some ss. i used to be a big firestone guy so i thought id give these a shot! > suicidedoors.com

i've had firestones and slams. Slams are by far my favorite bag. I love the stiffness of them, you can get away without running shocks up front if you run Slams, you cant do that with any other bag.

slams for sure. nothing else!

slams are stiff like dude said you can get aaway without shocks firestones and contitechs are nice also cant say anything bad about them

why would you not want to run shocks? are we that lazy ppl?!
as far as the bag situation goes ive only used firestone so i cant help much.
