Blackbird / SME

Hi all,
will a Sumiko Blackbird fit an SME 3009 improved ( non detach ) ? It is on a Thorens TD 125 mk II . Goes to a Manley Stingray through a Lounge Audio LCR. Thanks.

It's compliance the Birds is on the low side with the light 
SME non removable head shell version 3009.

That said compliance can be a strange "bird" pun intended.
Probably work with some additional weight added to both headshell (brass bolts) and counterweight.  As your headshell is fixed, be real careful with that naked cantilever.
It should be fine. The 3009 arms have a range from 6.5 to 12 grams. Find out the mass of that arm and do the math!
Go on Amazon and search for Technics Head shell weight. One should do it. If your resonance frequency winds up too low you can shave parts of the weight off with a Dremel tool to get it right 8-10 Hz. get the Hi FI News test record.
The 3009 improved with non detachable headshell has an effective mass of 6.5 grams and composite knife edge vertical bearing. IMHO, I would not go there. And it has more to do with the secondary resonances and bearing integrity than with the primary arm/cartridge resonance.
