I did some calculations based on 315.6g base weight:
315.6 + 10g silicone + 10g lead + 1g rubber band + 6g overgrip + ~15g? strings = 357.6g.
This compared to my #1's 348g, a 9g difference, strings can't account for that sort difference.
I'll get some more Tour Bite strings in and put them on scales and take it from there I guess...
