Which bags to use (not the same old question)

[1966ponyguy]

Ok, almost finished cleaning up the frame and getting ready to order the bags for my step-son's 68 C10 (now swb). Looking around the net and through the forums I am curious:

Suicide Doors have their bags (Firestone 2500 and 2600) both for $69.99.
Slam Specialities have the RE 6 and RE 7 bags (I think they are close to the Firestone 2500 and 2600) for $89.00. Street Ride Pro have their bags (BAGA-25A and BAGA-26A) for $49.00. Any guidance on what the true best deal is and is there any supporting vendors on here selling bags? From what I understand, I will need the 2500 on the front and the 2600 on the rear. I will probably order the a-arm plates from Suicide Doors as I have read several threads using them. On a different direction, I have a set of Firestone sleeve air springs with the following specs: 6 1/2" usable stroke, 750 lbs at 100 psi, 10 1/2 extended, 4" compressed, single 5/8 threaded on bottom, 3/4 threaded stud on top (fitting goes through top of stud). I haven't read anything about the sleeve type bags, are they useable, not really planning on hauling much in the truck.
