Big T, I recommend single foot guides. Why:
#1 - weight - less metal, half as much thread and epoxy = less fatigue after a long day
#2 - less friction when casting - this one I am not so sure of myself but a custom rod builder down south said that because the double foot guides have a much lower profile they cause more friction. A centre pin is deep (compared to a bait cast), the flatter the angle from the top of the spool where the line comes off to the first eye,the better, single foot guide is taller and there for has a flatter angle and this causes less friction.
I dont know if you have fished a centre pin befor, but I find you hold the rod out in front of your body more than a bait cast so I find my back can really feel it...trust me when i tell you the reduced weight of single foot guides is good.
The lamiglas I built (6-10lb) has a center pin handle and with small spin guides. I can use a pin or a spin cast reel on it. These rods arent cheap so I though by having spin guides, I could put on a light action reel and cast small jigs and spoons, otherwise use a pin for bait. i am very pleased with how it fishes!
