It's now more like a genuine 35# at 28", but I don't think it's made much difference, except maybe for the first shot. After that the bow had taken a little set.
I think I'm at the limit of the Hazel for that design... Maybe 3" extra limb length on each limb would help. I modelled it on the little Hazel 30# bow, but it has the lower limb about 30" and the upper 27"... by the well known law I happened to take the shorter limb.
Here are the speed figures:-
Out of interest the arrow with the 70gn point made 156.4fps.
I shall have another try for distance on a warmer day when the opportunity presents itself.
