How much of a difference would 25 more grains up front make as far as weakenin the spine. Would that be enough to see a difference or would more weight be recquired to see a noticeable difference in arrow performance???
Hunter Smith.
it took me 50 grains to see a differance in my arrows.
It will depend on how close to the edge you are on spine. I shoot woods and my experience is about like Bucky's, 1 lb for 10 grains.
When I shot gold tips with the insert that took weights in the back end of it. I always used weights in increments of 50Grs. Less than that never seemed to make that much of a difference with me IMHO.
This is timely for me! I just tuned a new RER Arroyo, with 125 gr field tips I saw a noticeable fishtail, but switched to 150gr and fly like darts. Like Fletcher stated, I may be right on the edge of the correct spine, but with this bow/setup, it made all the difference in the world. Just for reference:
RER arroyo 60#@28" (draw 28")
Beman 500 (7.3gr/lb) 29" (212gr)
8gr/" weight tube - 27" (216gr)
150 gr tip
total around 600gr or so
