Starperformer, thank you for your post. My point (which was in italics) is that I am speaking about me personally. As an 18 year old, the trumpet/cornet mouthpiece configuration gave such a HUGE advantage in tone and tuning against soprano cornet models back in 1983 (I played the latest Sovereign for 6 months prior). There was no comparison, and very little need for alternative fingering. I am practising for the Australian Open B flat cornet championship at present, and ON THAT I have to use a heap more alternative fingering for tuning than I do on the E flat trumpet. I have been doing studio recordings of my playing in the last year, and after listening critically, heard tuning deficiencies that were, except for my middle 'D', due to lapses in concentration, breathing, or general tuning from just not being able to hear the accompaniment through the cans - rather than genuine issues with instrument tuning.
I have actually wondered (as one friend suggested after playing it) whether my instrument (Yamaha YTR6610S)is a FREAK, one out-of-the box - I have to admit, I have not tried other models, or even another of the same model.
I took a break from full time banding between 1989 and 2006, but trialling some soprano cornets again in 2003 made me realise that, except for the Shilke, there has been no improvement in the quality of the other commercially available soprano cornets I have trialled since my old circa 1980 Sovereign. By some miracle, I coaxed a Besson to 2nd place behind Fitzy in the 2004 nationals (using a piccolo trumpet mouthpiece), and first in the 2005, despite having to play A flats with the third valve only, and the third slide fully out, and alternative fingerings all over the place - Why do soprano players put up with that??? Challenge the manufacturers, ask for your money back - it is NOT NORMAL OR ACCEPTABLE for a $4000 instrument
It troubles me that, in NZ anyway, we can't attract people to the instrument and that bands have to import soprano players from Australia and Britain every national contest. I'm not trying to say the E flat trumpet is the answer - it is for me, and I'm frustrated that it is not promoted as a viable option because of some "traditionalist" attitudes, backed up by supposedly bad experiences with E flat trumpets (whereas we have ALL experienced bad soprano cornet playing). If orchestras had the same attitude, they would still all be playing sakbuts and wooden cornets - and they are still adapting to things that give a superior result.
The strange thing is, I can play like a 'traditional' soprano cornet as well, but outside of Britain, the general public doesn't know what that is.
