Thank you for all your very helpful views, Gentlemen. After careful thought, and weighing up the pros & cons, together with the YM test report of the leading available props, I have ordered a Darglow Featherstream. As mentioned by Bob, astern performance is excellent, which is important in tight maneuvers. Not, cheap, but it does seem a good all-round solution. Awaiting delivery & installation, I will report back on my findings. Many thanks again for your trouble in answering. Hope to see some of you in Bembridge. Best regards, Bryan Hughes, Karisma.
