Just for balance I love double drive. I think it is easier once you learn to manage the momentum.
I would not reply except for this "loathing" thing where really really strong dislikes are expressed, and what if you others were successful in limiting this option and I wanted another wheel? Scotch tension brakes the whole system so if you stop treadling it just stops dead and you have to expend energy to start again. some confuse this with control. Guess it is of a sorts. Imagine if your car did this. For the record, I have a Lendrum upright and use it for plying because you can set it for strong pull, and as a go to meeting wheel. My regular spinning is done on a Watson Marie, which just spins wonderfully and productively. No flames please. Nancy
