Thank you for those very useful tips.. If I were to ever own one again (and I'm more than open to that idea) I'd give it a go. I gave my Vipermax away in late 2019 to a friend in need. I had been given it anyway but I had also just been given a Mercury S. His need was larger than mine, he was totally skint, I was at the limit of available storage space and, well, what goes around comes around, doesn't it? He loves it. As said, I'd be more than happy to have another one day to have a play with.
