Arrow weight vs lifesspan bow

[Flying Dutchman]

Hi gang,

another question about arrowweight. I always shoot woodies and with a 45 lbs bow I am around the 9,5 GPP as avarage. Sometimes more to the the 9, sometimes more to the 10, that just depends to the batch.

Now I am playing around with carbon. I found a setup that flies great, but it weighs only 8,2 GPP.

I would like to stay above the 9 GPP however because I heard stories that the lower the arrowweight, the shorter your bow will live.I shoot a hybrid longbow which is heavily reflexed and shoots very fast.

What are your thoughts?

I would believe you should stay around 9.5 gpi to 10 gpi to get the most "life " out of your bow  :eek:    :eek:

I could be wrong on this, but are you two confusing GPI (grains per inch) with GPP (grains per pound) when it comes to the warranty of a bow and/or the life span of a bow?

I say this because if you're dividing the total arrow weight by the bows poundage, that's the realm of GPP (grains per pound) and it's GPP which is very important to a bowyer's warranty/recommendation because shooting too light of an arrow can damage a riser or a bow's limbs and also, over time, shorten the life span of a bow.

Take my example. My 2212s weigh 8.8 GPI (grains per inch), but at the 421 grains overall finished arrow's weight divided by 42# means I'm shooting a 10.02 GPP (grains per pound) arrow. The same 421 grain arrow shot out of my 37# bow means I'm shooting an 11.37 GPP (grains per pound) arrow. These GPP's won't harm my bow or void my bowyer's recommendation.

If one would take a poll, I think the "majority" of bowhunters are shooting 10-12 GPP (grains per pound) arrows which seems to be a happy medium.

Thank you very much Joe, ofcourse I meant GPP! I corrected it. It was early this morning I guess..... I know the difference ofcourse between GPI and GPP, but I gues this morning my head meant GPP but my hands were typing GPI. Thanks again for correcting me in such a gentle and gentleman-like way!
