I know these are only reference tensions but #3 clearly was a bad one, I concluded.
I requested 62# but I think the stringer( person or machine ) probably pulled it at 70+ lbs.
It felt dead and I stopped playing with it. BT7 with this high tension is probably unusable.
There goes $43(string) + $22(stringing fee) wasted.
At shops around here you can get a good string job done for <$15... I personally charge $8 labor, but I get a fair amount in tips.
