I bought a SNOW viola in 2007 then I went from a 14.25 inch viola to a 15.5 inch viola. I tried getting used to it in college but had to switch majors due to a health issue so I never got used to it. I have just picked it up again and I am doing Schradieck. I'm having a really hard time I feel my like hand is excessively stretched and I'm having a hard time staying in tune. I don't remember feeling the sway on a 14.25 inch viola. Will a 15 inch viola make a big difference in comfort? I'm not trying to rock a baby viola again.
