Art:
I remembered that you recommended the 2216 in another thread.
Friend and I cancelled a half a day and a full day of hunting this weekend because both of us were still not satisfied with arrow flight. Sitting in field and constantly thinking about negative aspects about your gear and tune drastically affects your confidence and motivation.
To make a long story short, a full day of shooting in (again) this past Sunday revealed that all the pre-season shooting had restored the old " recurve" muscles and form, and (now) increased the necessary shaft length for both of us to 32" .
Additionally, we were able to lay our hands on some 2117' s, and although shorter than what our draw-length is, we were able to reasonably determine that the 2315' s we were shooting were the problem. Friend' s grouping came back onto POA, and my problem with occasional " porpoising" and " fishtailing" disappeared.
Now it is a matter of determining the better spine to go with without trial-shooting several spines because we do not have the time to do it without blowing a major portion of the " season." So I decided to to go the route as I have posted here.
Question, Art. Keeping in mind that friend is shooting off a " Fast Flite" string, and considering that that type of string is going to put some increased pressure on the shaft and possibly create a demand for more spine in the shaft, plus that he is shooting a 26 grn. bh adapter, do you believe he can get good flight with a 2216, or possibly he should go to a 32" @2219? I know that trying to mentally determine what may be the best spine is not the way to go, but because time is of the essence, we are forced to go with the best " off-shoulder" estimate at this time.
PS: Being able broadly seek input for this shooting situation (problem) confirms the beauty of the Internet and sites like this one.
