I am going to mess with my pro open and try some lead at 3 and 9. I am thinking 4, 4 inch strips at 3 and 9 should give me 8 pts or so of SW and a little more stability and plow. I use an overgrip (tourna). Do I need to counterbalance or in your experience is this pretty minimal in affecting balance considering the OG? I don't have a balance board unfortunately. If I decided to balance the bottom back..There is silicone in the handle..instead of using lead under, has anyone used screws into the silicone before and how did that go?
