Great idea
Haha, you have been persistent, and people have be deliberatly ignoring your question.
I’ll put you out of your misery, with my OPINION if you are interested
Your implant will be ~11mm
The FlexNT is 8mm
With the custom needle, it is JUST possible to use a custom needle, your extra 3mm doesn’t sound like much, but thats HUGE
Will your installer be comfortable ( or legally allowed) to use a scalpel? If so, THAT is your better option
