Imported Maple out in the desert today. I have this 2019 TMBR Irving set up with a maple 516 and some Zipline Kot-N today.
Watch out, man: they can get pretty addictive! I started with one SF era one; just got another. At some point I will try one of the BC era ones like you have
Playing one out of my 5/5 Top 5. When you play them a lot over time the cotton really smoothes out those axles giving great spin times but some sacrifice to response. Had to rough up the TMBR axle walls a tad to get that fresh snappy feeling again using an emery board. TMBR Maple Sullivan, Zipline [kot-n] and since it’s 5A May a TMBR Lil’ Barrel counterweight.
