I was wondering if Imeo ever made a self adjusting center pin like the one found on the ithaka. What I noticed is when attaching the iAtty on my gp paps, theirs a gap even after adjusting the center pin for the mod. I have the GGTS base on the iAtty at the moment and thought why not try the ithakas air flow control base on it. Fits perfect but the center pin isn't long enough. Hopefully Imeo has done it
