C'mon Ron
Being a stout traditionaist is fine. I love reading muzzleloader history - love to attend reenactment-events. But the actuality in my life says my inlines are:....... more accurate -- more resistant to moisture - can handle more powder -- can shoot a bullet flatter -- can shoot a bullet faster -- less moving parts -- easier to pull a load, then reuse it -- easier to clean with open breech -- easier to inspect -- hotter ignitions...... etc....etc...etc.
I own both sidehammers and inlines. But if you do not see progress with inlines, I'm not sure what your definition of progress is.
Progress is in the harvest and you have a better chance at a harvest (all things considered) with an inline.
