Hi TC,
I wouldn't concern myself whether it's Winter Green, Santa Ana or Windsor Green, It's all couch and it works the same way. It's a regenerative type spieces and the more you give it a hard time the more it will regenerate and grow to survive.
Cam's a top block and I've bought bucket loads from him over time. He looks after his customers really well.
The principles of setting one of these machines up is not rocket science but does require a bit of patience and thought. Once you've mastered it you'd never pay someone as much as they are asking for it ever again and thus you get far more economical use from your machine. It's the maintenance that has many folks walking away from these types over mowers in the long run. It's a skill you'd develop and thus once you got it you'll never lose it. Bit like riding a bike I guess.
Cheers,
BB.
