I haven't read the whole topic but I'll give you my opinion. This scheme is allowed in LW and I've been picking Pro for many years, I also played some Pro clanners when I was VW in FB. In my experience, the banana has never been a crucial weapon in any game I won (sth like the 90% in LW). This scheme is meant to be played in caverns, otherwise it's an elite with 30 seconds -I know that elite can be also played in caverns- but for me is a funny and interesting scheme.
People who compares Pro with other Animaniacs schemes are absolutely wrong and haven't even played this once, so I don't see the point of posting their useless comment.
Anyway, this scheme is not popular and will never be, but I give my support as Free league IS Free league, a place where we can play these forgotten and not so famous schemes.
