Why do these charts change??? I have one that came with a compound bow I bought used, the bow is 1991 vintage, and it has no relationship to the chart that I picked up in the "Pro Shop" in 1997. 60-65#, 125gr points 31" arrows: "Chart One" 2117 or 2216, "Chart Two" 2315 or 2219. Chart Two recommends the 2117/2216 for 45 – 50# bows. What is the deal??? Are these charts for "this years" bows only??? Should I look at a 1968 chart to get some idea what I should shoot out of my Bear recurve??? just wondering, the cedar shats maked 55-60 seem to work great… bd
Response:
The charts aren’t changed really to "this year’s" models like a car or anything. It’s revised every year when the testers go out and find that their original advise on the charts aren’t as good as they thought they were. Personally I find everything on the chart to be a little slightly weak for me, so I usually go look at the chart where I should be and go one size heavier (at least that is what I should be doing after experience). The chart is only a starting place to work from. It is not the definate answer to your arrow selection process. Han Su Kim

Han, when commenting on things like this it might be nice for you to consider indicating it is *your opinion* rather than *fact*. When you make an comment like this, in particular your comment on "testers", you lead people to share your incorrect conclusions. The charts and variable list is updated to reflect data gathered from the current bow market.
Response:
: The charts and variable list is updated to reflect data gathered from the : current bow market. To amplify on this. Except for traditional longbows and some recurves, most bows are faster than the bows just a few years ago. Radical cams have pushed compound speeds upward, and recurves have benefitted by the use of graphite and other composite materials in the limbs. refinements in design, and the use of virtually no stretch strings. To compensate for the greater force being applied to an arrow, a stiffer arrow must be used. And as has been said many times, the charts should get you close, and are a good place to start. The arrow flight simulator might get you a little closer, but it always comes down to a little trial and error, or a lot of experience to get a very closely matched arrow. I suspect that longbows haven’t gotten much faster so that yesterday’s arrow spined for 50lbs will be the same as tomorrow’s arrow spined for 50lbs. Marty Sasaki
Response:
Well about trial and error, I can atest for that, but it’s been a VERY EXPENSIVE process unfortunately. Wish there was a better way then to just use the charts and simulator, one giving too weak a result and one giving too stiff of a result. Han Su Kim
Response:
OH just thought of something else to add to … What exactly do you mean by reflected to the current bow market? Does that mean all new bows or most? Exactly how is the process done? How does Easton acutally come up with these results? Han Su Kim BTW How did you do at Gold Cup George?
