The 5th Horseman

Hey yall, Ive been a musician for 10+ years and mainly play guitar and piano, but I have experience with Clarinet (4 years). I have always been really interested learning how to play either violin or cello and im starting to feel more inclined to play cello because of its wider range. Im aware of Viola, but im also aware that there is no standard size for violas and there are a lot of variables and I dont want to have to contend with that. If anyone could give me any comments or anything regarding playing violin or cello, learning the instruments, nuances of the instruments, etc. Anything that could help me......aside from just saying " go try one"....I know that. I meant anything that I wouldnt be able to learn from playing one for 10 minutes testing it out. Thanks for any input
