With about 200 casts with every bait, I came across something interesting.

The quote-unquote Man Made Baits (Flies, and Minnows) - got Mech to Perplexing.

The quote-unquote Harder Baits (Cheese, Fish Eggs, Live Bait, Dead Fish) - kept Mech at Clear/Learning...

MECH 92 - Failing on all baits roughly 1 in 10.
