Dear Jazzgene,
let me address your last question first:
the UNI-Protractor works even with an Ikeda or a FR-7f - compared to these two cartridges' ultra low bodies, the Grado Statement is walking on stilts .....
The Jig you mentioned and use allows alignment only for either Stevenson IEC or one of 3 recommendations by it's manufacturer.
These e are suitable only for very modern records cut for audiophile purposes (like 45 rpm short cuts) or reissues.
The Stevenson IEC isn't all that great to start with, but try any of the three manufacturer's recommendations with an old Mercury, Impulse, Columbia, RCA LSC - in fact most any record from the 1960ies or 1970ies - and you will run into high distortion towards the last 1/2" of your records groove, as the derivation from the tangential ideal rises steep with these alignments.
These alignments are mainly suitable for the 9" tonearms of the jig's manufacturer and for records cut following IEC standards only and offering a rather small actually grooved area ending way apart from the inner label.
A rather specialized tool - and specialized for a very certain kind of records mainly, but even among those, there are pressings which will not really suitable to be tracked with such an alignment.
Cheers,
D.
