The best response for sure is "N+1". If you've never taken a statistics class or done a thesis that answer is lost. Nevertheless it best describes at least players who are trumpet enthusiasts and are likely found participating in forums, thankfully. The trumpet forum is like a support group for people who are powerless over the majesty and brilliance of trumpets and whose checkbook has been made unmanageable by that love.
I carried a Selmer K-Modified all through college and the next twenty years of playing, get rid of it? Never. But I always wanted to know what the big deal was with those Bach folks so somewhere in time I could not turn away a Strad at a garage sale for $250. Good buy, now I know what a Bach generally plays like. My teacher always talked about a 'big sound' and played a large bore horn, always. So I bought the large bore Yamaha and play it most of the time. It's a lightweight and I'll most likely never sell it just 'because'. Many of us find transposing a PITA hence a C horn in the stable. Mostly we simply like horns.
