I would humbly offer these suggestions:
1. Determine if you really need a rack. Racks (and rack gear) add size and considerable weight to your rig and unless you go all the way and buy a shock mounted rack, you're only protecting your gear against scratches.
2. If you do decide on a rack, remember to consider a few things like being able to lift it by yourself, getting it in and out of your vehicle without damaging either, and making sure your rack has sufficient air-flow for your amp since most folks cram their racks full of gear.
One last suggestion: you mentioned that you had very large pedal board full of effects. Don't forget that the best (or at least the truest) tone is achieved by the shortest signal path. Try keeping the pedals and patch cords to a minimum. If you really use every pedal during a gig, make sure there's a pedal in the middle of the chain that is buffered so you don't suffer the usual signal loss. Think of it this way: if a decent instrument cable starts to suffer signal loss at 25 feet, imagine what happens with 12 patch cables going through 10 pedals.
Just food for thought...YMMV
