RE: Cedar Arrows
First, let me say that what arrow any of us would shoot from the same bow will vary. To get the best arrow for your brother to shoot from his bow, you' ll need to call a reputable fletcher and get a set of tuning arrows. They will generally be in 2 or 3 different spine groups. Something in the range of 45-50, 50-55 and 55-60, depending on what he' s actually pulling with the bow, the length the arrow will need to be BOP, the design of the bow, the type of string being used and your brothers release, as all will effect what spine will actually fly well from the bow.
As an example, my 60" CM hunter II takedown recurve is 51# @28" and with taking all of the above criteria into account, the bow shoots a 28" 55-60 spined cedar arrow perfectly with broadheads attached. My 1967 Black Widow recurve at 50# shot a 50-55 spined arrow. The primary difference between the two bows was the string material. The old widow shot dacron and the CM shoots dynaflight97, which boosts performance on a bow by about 10% over dacron. However, you' ll need to know whether or not the bow will accept dyna or any other high performance, low stretch string material without damage before using it.
I pretty much shoot cedar exclusively. I still have arrows that I bought more than a few years ago. I shoot them daily for all of my practice and hunting. I stump shoot daily and over the last couple of months, I' ve broken a half dozen arrows. There' s just something about the feel and smell of a good cedar arrow when stalking ancient cedar stumps in a lush forest. Know what I mean?
