Twin/triple plate clutches only have one pressure plate. The advantage to a multi-plate setup is you have more surface area for the clutch to grab. This allows them to hold more power while also keeping the PP clamping load lower. In order for a single plate clutch to hold equal amounts as a multi you have to ramp up the clamping load on the PP. This in turn creates the "heavy" clutch feeling. The more clamping load, the heavier they are, generally speaking anyway. There are a lot of other factors that go into making a good clutch though.
