Vice-versa also applies, assuming your drivetrain is fit to be under the stress of the sum of torque from all rotating masses.

Single, twin, and triple discs all have different arguements of why which is better for whatever application. However, if torque capacity is your only variable, a single disc can hold just as much as a triple disc, depending on clutch material, size, and pressure plate specs.

The more $ a clutch is, doesn't neccessarily mean its better for your application.

Slipping clutches isn't a bad thing... if your clutch didn't slip from launching from a dig, and you make a lot more torque than your drivetrain is designed for, you might be having a bad weekend.
I will have to disagree with some of the last part of your statement. A single disk will not hold as much as a twin or a triple. I know clutch material has a good bit to do with holding capacities but the single disks just dont have enough surface area. The twin disk's 2 disk's have more of a surface area thus holding more torque than the single. A Carbon/carbon is probably the best twin but are in the $2k range for hondas so I can imagine what the cost is for something else. With the carbon/carbon clutches, the hotter the clutch gets the more holding force they have. Some of the drag racing guys with these clutches use the Tilton release valve which regulates fluid pressure upon engagement letting the clutch slip a little which is good for launches. This is not so great on a ceramic twin disk b/c the hotter it gets the less it holds. Twin disk will last you a long time in drag racing, but street driving is what kills them. Not to mention the pressure plate on a twin disk is usually not a bitch to push in. Triple plate I dont know much about.
But I do agree with you on the getting the proper clutch for your torque application. It kills me when someone gets a stage 4 when they only needed a 1 or 2. I would rather go with the weaker of the clutches that I could use just for the pedal feel and ease of engagement. Usually the easier it is to work the clutch the easier it is to launch well.
