Thanks for that, I like the bkool app even with it's issues, I don't find zwift as good, but my wife and son use zwift so I need a training that works for all three of us (hence no direct drive turbo). It would be a shame to leave bkool as I've used it for three years, but I've had two of their turbos fail on me. Just waiting on wiggle to refund me then I'll order the snap and see how I get on with it and bkool.
