Jawge, I've only built about 4 "successful" bows. The others don't count.
Since you mentioned going wider, would you give a recommendation...I'm shooting for a about 64" and 50# at about 26" or 27". I was thinking 1.5" at fade with either a straight taper or carrying the width out 1/3 and then taper to .5" tips.
Before I start, I may go and look over the other staves from this tree to see if any others are better. I had started a bow from the same tree, but the stave was either from a different section or perhaps just from the other side of the log, but it had better rings (lopsided rings), but it ended up being scrapped due to some severe wind checks. I had it down to the final ring and even cut out and almost floor tillered when I decided the checks were too bad.
