I didn't know anything of flugels, played an eterna of a colegue and bougt one from ebay. after i got the chance to try some others (courtois, yamies, bessons) I noticed, what a... lets say "for me unfitting" can I bought. it doesn't work above mid G at all, intonation is horrible and the sound realy isn`t soft as a flugel should be. playd 2 more of these and they were the same. I was happy to get rid of it without loosing any money. tried a lawler with the getzen valve stock and i had the same problems (well the sound was softer), maybe i just don't get along with the large bore flugels. the yamaha 631 i play now is much better, up to hich c i feel very comfortable, but there are even better ones, like the kanstul 1525, that play great, even above high c.
