Z-stack AND PGM question

Do the YYF Z-Stacks fit on the PGM V2 and do they any effect on the stability thanks

This has been asked many times before. Yes, they fit but they cause the PGM to wobble to a point where it is unplayable.

lol it makes it 100% unplayable, but its funny just to see it happen

Ok thanks, dice stacks it is then.
