that's interesting that you say there will be a new Mako mold. Nothing wrong with this one, I don't think.
When new, the Mako was the straightest disc I've ever thrown. A tiny turn, no real fade either, just straight. Since I beat one up it got pretty flippy and touchy but when I was new I had a mako and a roc as mids and it worked well for me. Maybe I didn't have the power to flip the Mako then, but I do now, or something. I don't usually bag it, but I still throw it in the field, or on wooded courses where you need a super straight shot from a standstill.
I'm a big fan of the softer star blend that Innova uses for mids like the Mako. Wish they'd make faster discs with that blend. Grippy and softish, but not as floppy as FLX. Good in the cold. I'd think a fairway driver would be great in that plastic b/c it absorbs tree hits really well and doesn't skip away. Oh well, one can dream.
