I like how they say "enjoyed mastering" then go on to say it "presented inconsistency problems" haha. Doesn't sound like they mastered it to me!
Interesting take on it though, makes you wonder if they didn't come up with a good enough design or if gyro is just a gimmick. Or if their ultimate goal was measured in distance (or flight path) and if perhaps the hassle and cost were too much and that's a cute little slam against all things gyro. IE costs too much to make, minor improvements in flight, so let's just say it sucks and drop the overmold line.
You know I posted this but glossed over that point. They're inconsistently mastered is all I can think of now hahaha.
I'd lean with costs. I personally have never seen anyone throw Lat's overmolds or in the used bins. However, I like the questions you posed and actually wonder if it's costs, excess bulk due to poor demand, inconsistency, or another issue.
