Why would the W.B. have any affect as far as the size of the hole for the arrow
The Super slims are just that; very small in diameter I don't know how they would compare to your current arrow. It may or may not have an affect on your shooting.
I do like the weight of the cx edge arrows, about 10.3 grains I think.. I'd like to stay somewhere in that range
You won't have a weight issue (to light) with the Super Slims. Size 400 is 9.7 grains per inch, size 340 is 10.7 grains per inch, and size 300 is 11.5 grains per inch.
Straightness: +/- .002 guaranteed. Weight tolerance: +/- 0.5 grains. Both are the same as the ACC line....
