I am tilting towards 44x7. The simp,e reason being, I will change my tt in about a year. So would decide on the new cartridge then.
Denzong,
The Ortofon is upgradable with styluses you can just plug in, the 30 and 40 are supposed to be good upgrades, plus you can plug in a stylus assembly for 78s too. Do consider that route too before deciding. A tough choice given the quality of both and the similar prices...
