My knowledge of the two Funtanas is second hand, but does come from a good flyer. He said the 1.25 is improved but not night and day. It is more stable in a harrier and the coupling in KE is improved. I only have the old yellow Funtana so I can't give you the complete picture. For my part either Funtana should out fly the SG edge. At least for 3D type flying.
