Matt, I went through my stack of Lancair Mail newsletters since I remembered a short article regarding your question.  On Issue No.1, 1st QTR 99, page 8, you'll find the following article:

===========================
LANCAIR 320/360 CG LIMITS
Recently both Orin, with his MK-II tail and Doug, with his standard tail configured 320 performed some flight tests with adjusted fwd CG's.  Basically, they flew with a slightly forward CG to define how much farther forward acceptable flight and most importantly, flair to a landing could be maintained.  the standard, smaller tailed 320's played out a little sooner but a fwd limit of 11% worked quite nicely.  both reported good authority at the flair and enhanced stability as they moved the CG forward.  This 11% of MAC should be considered since it offers greater overall CG travel before getting too far aft-which is ofcourse, something to be avoided.
===========================

So it looks like that going forward 11% of MAC is acceptable but it doesn't mention moving the aft CG limit forward as well...
