contitech bags

So I am gathering my things up for baggin my truck. I already did a search and couldn't find what I am looking for about contitech bags, so here it goes.
I am gong to mup them up front and was wondering if any of you aout there are running them and what combo you are running and or know would fit with out major adjustments like notching into the frame, The options I am looking at are 2500 and the 2600 2 ply or 4 ply. This is my first bagged attempt.
So far I have the viar 480, 8 gallon tank, 3 1/2 smc valves for fill and 3 3/8 smc valves for dump, toggles relays, and fuse holder, 145/175 pressure switch, and bag brackets. My next buy will be the bags.
I am not looking to hop or anything. I am looking to get the 2500 for size and 2 ply because it needs less psi adjustment for range of motion but dont know if this is too wimpy of a bag and will hold up.
Any replies or advice is greatly appreciated. Thanks
