I play tested the R&C saxello comparing it to several yanis s6, 901,991(with stock and silver neck), and the silver body Elimona model and a true tone poorly set up..
For me tone-wise the true tone(even though it was poorly set up) and the s6 were the best, then came the silver Elimona (split body), then the R&C and then the rest of the yanis.
Ergos on modern yanis were the best, s6 and true tone have some issues that are easy to overcome but the R&C was the WORST(by far) .. some features on the key layout were made in a way that made me wonder what was in their mind when they were designing this mechanism. The owner of the store and the tech agreed with me..
I went to that store and I really wanted to like that silver r&C saxello but after trying to play it there is no way I will ever buy one..
I don't know if this happened because I have large palms (this has never been an issue on any other sax, ever) , maybe it will fit someone with smaller palms.
Or maybe if I play only this horn for a month I would get used to it..
I haven't played on the Cannonball or Mauriat saxellos but I surely would not buy the R&C eventhough it looks amazing..
Clearly the toughest key layout out there..at least for me.
