Sirspeedy I don't think I'm qualified to advise you. However I went back to the spreadsheet and that cartridge in tigerwood/jacaranda gives a resonant frequency of 8.66 Hz. The ideal range "green zone" is 9 to 11 Hz, however on AJ Van den Hul's site, the 'yellow zone' is 8 to 12 Hz.
On that basis, I reckon either of those are viable.
I was tempted by bocote for my Reference but checking out the pics on Thom's site, I don't like the look of the wood. I also looked at the cartridges that it would allow me to run and, in reality, everything I would want to play with (Koetsus, DL-103 and Dyna XX-2) work better in a 15g armwand. I like the look of jacaranda over tigerwood, so that's what I'm getting.
You have to remember that it's not just the cartridge mass, but also the compliance that counts. Low compliance favors higher mass tonearms.
If you're thinking of buying a Schroeder, if you order now you'll be lucky to take delivery this year. I reckon that's far enough away for you to enjoy a state of the art tennis racket this season and still be able to pay for your arm when it's ready in the new year!
Put your order down, you know it makes sense! :-)
