I've noticed they are generally better also and make a decent foundation for a very good single stage FCG if one doesn't mind actually using the rare pieces. Probably quality control that hadn't been corner cut to death since it's introduction for reasoning. Current production S in square for coins is probably the best readily available today until one steps up to aftermarket. The dot marked stuff pretty much blows and most should be ashamed to even call those American manufactured from the few I've actually used.
Looking back I probably regret neutering the 01 units although my justification was nothing spent vs spending a few coins, resources and the time factor. It's what I had on hand to complete a build. Hindsight I should have sold the 01 pieces and not neuter them or simply bought something better with sales profits but my decision to put something together immediately and shoot it outweighed the better judgement call of wait and purchase an aftermaket or not use a fairly rare FCG. I also prefer a modified single stage over a two stage in most shooting applications. Possibly if I had been brought up on Geisselle or such I would have a different opinion.
Good to better shooters can generally make most anything work with better than decent results without breaking the bank also. Hence the 39/40 score with a well worn nothing special weapon. Nice shooting.
