Yes, GO FOR IT!!
Anyway, Colin, an instrument of your choice?? Wow, I'd have loved that! At our school all they had on offer was the Clarinet or the Flute, so I picked the Clarinet as it had a much more *manly* sound (bearing in mind I was about 10!

) and played it up until a few years ago (I keep meaning to get back to it).
However, if I'd had the choice, I'd have undoubtedly learned the Double Bass, Cello, or Percussion. Violins were always 'dead common' to me (and I was strangely indifferent about the Viola. Yes, I knew what it was, but I just didn't appreciate it for years). I also need to point out that my Dad used to take me to some of the (R)SNO Proms as a kid, first at The Kelvin Hall, and then the Glasgow Concert Hall, so I knew fine well what all the different instruments were. The double basses fascinated me because they were just SO big (bigger than me at the time), whereas the cellos were often right in front of where I was, so I spent many an hour just watching people play them - every stroke or tap of the bow, every funny little 'wobbly' note they did with their fingers, every subtle little movement, every tiny nuance, everything. Heck I probably could still recognise the players as it was often the same people sat in the same place every week or whatever it was.
Even now I flirt with the idea of buying a Viola or Double Bass (the bass was always my first love despite spending all that time watching cellos) and start playing it (I notice there is a local band near to me who is, or at least was, always looking for Bass players).
Except for piano, if you had had the choice, what would you have played out of curiosity?
Sorry, not much use to 'The Tuba Set' which this thread is aimed at.
