A way I have found to remove a metal shaft butt weight without endangering the graphite shaft is to heat up the end of a metal rod with a torch then hold the heated end of the rod againt the metal butt weight without touching the graphite shaft at all. Sometimes it take 2 or 3 heatings for the weight to come loose. This assumes there is a way to grab the weight with pliers or insert a screw to pull it out. I test it after each heating until it pulls out as to not over heat the weight and the shaft.
Obviously this doesn’t apply to Tour Lock nor Balance-Certified butt weights which are held in by rubber grommets that at squashed and expand to lock in. They require the proper wrench to loosen and remove. Sometimes those still require pliers to pull out if the rubber has been squashed for so long that it doesn’t want to let go.
I am not sure if Odyssey epoxies or somehow secures the weight in the butt end of the Stroke Lab putters. It is a brass weight so I would not recommend drilling it out. Drilling builds heat and you would damage the butt end of the graphite shaft. If the weight has been secured with epoxy or say Loctite you will need to very carefully heat the butt end of the shaft to break the bond so that you can remove the weight. I would then expect that you should be able to install the Super Stroke Counter-Core grip and weight but I do not have an ID measurement at the butt end of the Stroke Lab shaft to know for sure if the Counter-Core grip and weight will fit.
