I have a similar set up
70 Airsal (small port)
15 sha
Airsal carbon fiber reeds
Le Partie cdi
Polini Country pipe
Honestly the sha is a bit boggy for this set up, and I love me a sha, you'd be better off sticking with your present reeds and ordering a PHBG set up, I know its a bit more money, but mannnn my sha is hurting on there, I just ordered a 19 PHBG and will be swapping it out tomorrow
