14x9 NFA Solid or 14 NFA Round Solid

Well - My trusty 14x7 NFA has finally come apart at the seams .. Where the stem mount attaches to
the coil has seperated ( 2 of the 3 plastic rivets have let go & the coil is sort of floating in the breeze )
Still works fine but time to send it off to Rohan from Nugget Finder for repairs .
I am now contemplating replacing old trusty with either a 14x9 Solid or a 14 Round Solid as my general search coil ...
If any other members out there have used these new generation solids from Nugget Finder i would love
to read your comments about them - Good or Bad . My 14x7 will become my spare if i choose to go with
either of these coils ...
Thanks for any feedback.
Cheers
