Hi guys.  I'm aware Aerodyne have their own sizing charts etc but just wanted to ask you guys and gals a quick question.  I'm jumping a Spectre 170 in my Icon I5 Nexgen but want to downsize to a Safre 3 149. Is this doable?  Aerodyne recommends a 168-1880 Aerodyne canopy but, what about a Safire 149?  Any advice would be welcome.  Many thanks!
