Just purchased my first Scotty second hand. It’s a select Newport 2.0 dual balance 2014 model. It came with a after market super stroke countercore grip. I would like to go back to an original Scotty grip but it says no weight supplied. Can you buy weights or is the weight in the shaft already. If I do need to buy weight how do I work out what weight is needed. The putter has 2 x 10g weights as pictured. Any help would be appreciated.
