I think your line "hardest fish to catch" is the key thing in all this. In my experience of owning this lodge(3 seasons) people are happy just to catch something and don't want to spend all day just for one even if it would be big.
The no tournament scene definitely limits the muskie lure production as well, no big money behind this stuff unlike the bass market. Which is just fine in my opinion. Muskie fishing is a very niche market, we don't cater to the hardcore fishing guys as some lodges do but even after specifically advertising to muskie fisherman because our season opens earlier than Nipissing we had little interest.
I think the younger generation or say the generation with kids in the pre teen stages also don't want to go out all day and maybe catch one. It's not very fun not catching fish of course for younger people.
