I have a couple of Countryman E6s & dPA fine's at my disposal. OP was not about how to get good hands free sound.
Frankly, I was curious if mic element size played a role-perhaps affecting my choice or decision to try a different lavalier.
There are those in our "circle" that are opposed to headset/ earworn mics- many opposed lavaliers a couple decades ago. Admittedly irrational- but a product of some who allowed technology to change them. This was a unique situation where a physical impediment made a handheld impractical- at the same time making it awkward for someone unfamiliar or uncomfortable with a earworn mic to be introduced to one.
In this application, seeing the lavalier is imaterial. if a larger lavalier can-because of the physics involved- perform better, then I would like to pursue that option.
