Chuck----if you can give us some info on your setup it would be much appreciated
The 200 and 300 means spine,meaning how much it gives and flexes.
If you are shooting a fairly high poundage bow with an average draw of say 28-29 inches and arrows are cut to 28 inches then the 300 may be a better arrow for you,especially if your shooting a single cam bow.They tend to like a stiffer spine more.Shows even more when shooting broadheads.
I found 2 brands of the carbon force
1 being the Dominator------.006 straightness
2 being the extreme---------.003 straightness
In hunting situations it really dosnt make much difference about the straightness out to say 20-25 yards
now---the 200 is 6.7 Grains Per Inch--spine----.424
and 300 is 7.8 GPI--------------------spine----.359
I can say you are still over the 5 grains minimum to safely shoot the bow.
You havent noticed any difference in trajectory shooting the lighter arrow?
I am shooting a Bowtech Patriot SC----27 inch draw----68 lbs and arrows cut to 28 inches.I was shooting Easton epics 400(spine)and the bow shot horrible for me,just couldent get it to tune.
Switched to Carbon Express CX 300(Much stiffer spine)and its shooting great for me,especially with the broadheads(Boss Wasp)
I would like to hear more info on your bow though
Is there anyway you can trade them in for the 300"s ?
