I would not say "small and weak"....maybe smaller
, but JJ are nothing to scoff at and probably overkill for a lot of people's apps and uses.
Though I REALLY like how they put them together with the setscrew...the JJs are a PITA to rebuild, unless you have the Currie exclusive tool. If I ever replace my joints are need new ones they will be ballisitc fabs
See the 2.63" joints are CHEAP right now too....38 bucks each!
