Flooring Tile - wet saw blade choice

I am a remodeling contractor.
I have had an MK-101 wet saw for several years. It is only used about twice a year to do a single room each job.
It is time to replace the original blade.
My jobs are ceramic or marble with the occasional patio brick job in the mix.
Which blade will produce the best cuts (fewest chip-outs) in marble?
What advantage (if any) is there in the new "Hot Dog" blades?
Is there any reason to purchase anything other than a standard quality blade?

Thanks

The hot dog blade is great for porcelain and granite tiles, but if your not cutting those, your wasting blade life using it to cut those other tiles, as any standard diamond blade will do fine. If I were you, I'd pick up a vented blade for the brick work though as the thickness of the brick alone will cause a tremendous amout of heat build up that can warp your blade.
