Got to agree there, I'm in the Isle of Man this week & have been playing with my FWB today, similar results, but aren't they hold-sensitive?
Mine's a Bowkett conversion & has a very quick snappy firing cycle. The closest comparison would be a gasram rifle.
Very much ahead of their time, well engineered, mine (a Mk1) also has a beech stock that is nicer than a lot of walnut stocks I've seen.
