if you attach a bowquiver to your bow, does this affect the spinevalue of your arrow? I read somewhere you should go 5 lbs lower in spine with a boa.
I want to use the Thunderhorn Small Fry Boa, which weighs 10 oz inclusive arrows.
I wouldn't think it would unless you put wrap around mounts in a working section of the limb.
...but I'm not REALLY sure...
The quiver is attached with rubber straps just at the fade-out area of the limbs
about 30 years ago I wrote a research paper about this. I have long since misplaced it. there were several studies that showed without a doubt tat attachhing a quiver caused changes in the harmonic vibrations in the bow that affected tuning. They were not big changes. Would it make you miss a deer, probably not, but if using a bow quiver in contests you should definitely tune your bow with the quiver on. The number of arrows in the quiver also changed things vey slightly
On my Hill style bows it makes a big difference, my Shrews dont seem to care.

It seems to matter most on bows with light risers and not cut close to center. As the arrow is released, it presses against the side of the shelf and moves the bow slightly. The added weight of the quiver reduces how much the bow moves, so now the arrow has more bow to get around, which requires a bit softer spine. Anymore, I paper tune with the quiver on or off, depending on how I'm gonna shoot. With my longbows cut 1/8+ out, it will make 3-5 lbs spine difference.
For a right hand shooter, arrows sometimes will shoot to the left. Just raise your brace hight up until your arrows are shooting true.
this is interesting.
indeed
In my admittedly small sample of bows I've not seen a difference.....only change I've seen is that the added mass of the quiver/arrows can tone down handshock/vibrations a little.
