Researched, read forums, , emails to BK, ETC seeking GMT 2 SS ceramic with correct hand stack, problem-free movement and can't find the solution. Purchased great sub from Toro and have GMT bug. BK has been extremely courteous with suggestions for an amazing sub but heart is set on gmt. He has candidly informed me he doesn't offer at present BC of movement issues, and im at a loss for finding what I want. Any insight is appreciated.
