I know people have mentioned this elsewhere but thought it worth creating a dedicated thread.
Last week Jack from JJP essentially said that the new I/o board used in Elton, the flippers of which are universally agreed to have corrected the jjp mushyness problem, will also be made available for other JJp titles, namely, GNR and wonka, so that they too could share the flipper improvements.
The board is 400 bucks from pinball life, but people have bought and installed it, and reported back that flipper feel is markededly improved.
Since then, some people have been investigating the changes, which appear to simply be larger caps on the 75v flipper line. Some have gone so far as to retrofit existing I/o boards (only changing out the caps) - with the same improvements

Apparently this will get you to TS4/GF flippers. Elton is better again because of the new coils used.
Literal game changer for JJp owners.
