The Mørch should work just fine with the Rosewood, especially with a blue arm tube. Way back I tested an Onyx Platinum in my (then) Syrinx PU3b with an effective mass of 11g and it worked beautifully.
The paramount issues are the quality of the arm’s bearings, its general construction quality and tolerances, not adherence to a compatibility table which dates from the 50s and is likely quite incorrect. The Mørch scores high on all three and I’d have no doubts about using it with a Rosewood.
I’d still buy the Colibri though.
