Changeable gullets do NOT ensure the correct fit. It's much more to the fit then just width. Doesn't matter what gullet I use Wintec will NOT fit either of my mares, because the curve of the Wintec is different from their back curve. Also BO is not an expert unless she does it professionally, and with english saddle fit it's always the safest to go with the expert.
Hopefully the problem will go away when you switch back to old saddle. Good luck!
