Folding 21inch JLP board w Noj 1950
Hi Krames - Here's my 1950 noj over a 2inch Drueke. Its def playable, see below and hope it helps your decision.




I also find 57mm/2.25" too big. 55mm is the max I would go, 53mm is the perfect size for me but unfortunately no modern boards come in that 53mm size anymore.
For daily use I play on a 2.25 with 1950 dub. To my surprise the original dub board was 60mm squares.
