G2 and A2 is the point where the upper and lower octave vents change over. I always suspect something is amiss in the octave mechanism when those two notes are at issue.
Another problem area could be the G# not fully closing. Look closely at those mechanisms to ensure they are working properly.
I've never used palm D for D2 but I suppose it could be done.
All used reeds warp when they dry out - even those placed in a tight reed holder. It should not be a problem - just wet the reed in your mouth or soak it in a glass of water before playing. When re-wetted, the reed will flatten out. DAVE
