Hi again,
Yeah it is good, excellent relaxation. The bow is just over 40lbs at my titchy draw length. It's black walnut with a hickory back. It was bought as "complete" from Rudderbows in the US but we found that they're not quite up to speed on the definition of a longbow "English style", so a very excellent man in our club whittled and fettled until he made a gorgeous bow of it. I have the same problem as you LMP; The bow's great but this nugget needs to work harder. I've found it much better when I realised that I don't have to hold on for grim death - my grip is now as relaxed as on the recurve and this sure improved the groups (when I remember to aim properly and remember there's no cut out).
Thanks for your comments everyone. have to work on GMB now, next posting on this subject will probably be in fifty years then!
