I am new to bowhunting, just bought my new Firecat and have yet to buy arrows. I am currently set up for 29"DL and 29" arrow length with 70#DW, I will be using a 125gr BH and feild points. If I am corrrect I should fall somewhere between .300 and .340 spine. Is this correct? If so, then if I turn down draw weight to say 67# then would i be at .340 spine? Would the weight savings of a .340 arrow make up for the speed loss of less draw weight? I can comfortably draw 70# so that is not a concern.

Any help will be grteatly appreciated.

I Have been going threw the same thing.340 will be border line for your set up. I would go with the 300 spine,always better to be a little stiffer then border line.Then if you want to stay at 70# there will not be any issue.I had to drop from 67# to 63# because I could not paper or BH tune , And most of all I have 2 dozen arrows with not enough spine.

Thanks RobD. I have another question. I will be hunting Elk and Moose here in Northern Alberta, so what will be a better combo:
I will be using CX arrows
If I use a .300 shaft instead of a .340 shaft the weight difference will be approx. 45 grs. so:
Is it better to shoot an arrow that weighs a total of 410grs incl. a 125 gr BH
or
an arrow that weighs 430grs incl a 100 gr BH.

I don't mind spending money on good equipment but time is at a premium so I could use all the info I can get.

Thanks::):)

Broadhead weight doesn't matter except that normally a heavier one will have thicker blades and/or larger cutting dia. Not a big difference in weight for those two choices any way.

Go with the .300 spine. :)

Not having all the figues, but between the two I'd probably opt for the one with a 125 grain head. It most likely has a better FOC.

Diffidently the 410grs incl. a 125 gr BH. That will have better penetration.

THANKS:D I really appreciate the help.Like I said I am new to the sport. This Firecat is my first bow and so far I think I made a good choice. I will report back after I buy the arrows and points and get some shooting in.
