The thing about clutches, is that by their nature, they like to be either idling or fully engaged - They don't do well in between.
That's why they're preferred for racing - They transmit full power once locked up. And for racing, they're always locked up.
For low speed, or off road use, where you're constantly changing speed, the TC wins hands down - I'm a believer.
I just picked up another used CT200U for my wife - The bike was straight chained as found, no jack shaft, just the clutch (new) and rear sprocket.
My wife rode it briefly around the property, the way she does mine (with torque converter) - Up and down little hills, weaving around outbuildings, speeding up, slowing down, etc . She came back after less than 5 minutes, with the clutch literally smoking.
I have to believe the factories put clutches on these little bikes, for only one reason - They're cheap.
