I think your plan makes good sense. I have posted several times about my hemoptysis. It’s very infrequent now & I attribute that to upgrading from 3% saline to 7% saline. I, like you, am very active (walking not running at age 72) & spend lots of time outside gardening. I do have a cough, but few other symptoms of bronchiectasis & MAC. I hope you continue to feel well. Take care.
