I think that I really understand your dilemma; if possible - try to test play both guitars/models, possibly in a company of musician friend, maybe a teacher, who would play the instruments for you and who would serve as advisor.
If this is not possible then I would try to find a friendly person who has an access to both guitars and ask this person not only for his/her opinion but also for test playing it for me via Skype or similar remote service. This was the case with me and my Antonio Picado model 60 - I am eternally grateful to my dear Friend - Maestro Eliseo Fresquet Serret who has played his Picado guitars for me and has been answering my numerous questions via Skype. I have proceed in similar way with my other guitar - the son of a seller - a student in music school played the guitar for me via Skype and then I decided to but this instrument.
Antonio Picado, model 60, 2015, Cedar/IRW. Scale 640 mm.
