Is the 14 Mhz hack worth it!

IIRC there were some pretty ugly 14MHz hacks back in the day.
Later I seem to remember there popping up some proper ones that synced down to 7MHz when bus access was needed.
I would go for a 68010 if already trying out 14MHz to get those few extra percent more, at least if you have fastram.

Well, I think the first ones did indeed upset the CIAs.
Something like lift up a pin and solder it to a 14MHz clock or 28MHz with a divide by 2 chip inbetween.
