Aaran, I love 'em!
Have used the MF40s but found them a little small and subject to bite offs from everything with teeth. Then tried the MF50 and had a couple of good hook-ups with snapper but small trebles resulted in hooks beeing pulled.
Now use the MF60 and caught three small snapper on my first three casts. Yet to hook-up to anything of size.
My favourite colours are the pale watermelon and the darker green with the gold stripes. They work well when you bounce them across the bottom but even better as a deadstick...
Hope this helps
