Both the Hadcock and HR100 are well documented as an excellent match for the London Decca.
Conventional theory might say the Decca is low compliance but it clearly works in its own way.

Check out the BAD, VERY BAD rsults you get with your match
The frequency sweep on the 1st graph should all be in the green zone.
1st graph - The Hadcock has an Eff Mass off 6, Freq Res is almost completely outside the green OK area. About the worst match you can get.
2nd graph - Tonearm with Eff Mass of 20, response in nicely in the green area, good match
Cheers

I cannot see from the capture all the figures you entered but as earlier reply. The London Decca does not apply to the standard theory. It is said to have a low vertical compliance but a high horizontal one.
The Hadcock is a known excellent pairing and similar in design to the the old Decca arms.
The Alphason HR100 is a low mid arm but noted by a number of owners as a very good match also.
Some heavier arms are also recommended.
With the Decca the control / damping of vibration is said to be the leading factor.
I am of course going on what I have read at this stage but have spent a lot of time looking into it.
