Z28 poundage

[BBGuns]

My 08.5 Z28 after new Wolfden string-cables and tuning was sitting on 71 lbs. Measured it the other day it was 68.5. Twisted the cables up a bit and got it to 69.5. Would untwisting the string a few turns get me another pound or so and keep my brace height at 8in?

untwisting the string will increase weight but it will also lengthen dl some and shorten bh I think.
