If I was gonna get a Helix I would go with at least a 8 instead of the 7 because of the mega plus imaging and also I believe that I read where the new mega live that bird is supposed to be coming out with just is compatible with the mega plus units that are g3n or the newer g4n. I use g3n 10 and 7 inch birds and really like mine. Also use an ultrex trolling motor on my old beat up 94 Javelin
