Anahata - a friend once suggested, to overcome the problem of the suck/blow anomaly, I should pull out on the bass hand and push in on the treble. I couldn't break it to him that it would just result in moving from one side of the room to the other in total silence.

When I changed from hohners (Bmaj) to a saltarelle (Bmin) I was totally non-plussed and thought there'd been a mistake. Then I finally understood and it opened up so many harmonic doors. I've recently had a hohner pokerwork refurbished and had the Bmin installed (actually it's a C/F box so the chord is Amin, but you know what I mean).
