Cuprajake Thanks for that. I take from that its ok if the flow is more or less stopped but don’t overtighten the needle down in the process, which is probably what the guy from BB was maybe alluding to. The great thing in watching Dave do a video is that he not only shows you hands on, but also tells you what he is doing at the time, which is the pro way of doing a video imo. Would have been better if the BB guy demonstrated what he was saying by actually doing it.
