How much does adding weight tubes affect the spine of arrows. Id like to add some to my 35/55 gold tips.

I never could tell the difference when I used the 3 gpi tubes in Gold Tips. Tuned the same with or without. It may effect the spine if you use some of the heavier ones, but I don't know first hand. You may get more response if you ask this in the POWOW forum.
I've used the 5gr in 3555 GT arrows, the spine was not changed as far as I can see. I'm pulling 45@26".
