Just looked at a Trapper at a local shop, I like! My Hybrid 46 just got out of ATF jail (14 months) that I intend to use on my .450 BM. I have several .45-70s but none threaded, so the wheels are turning. I hate to cut and thread my '73 vintage Marlin '95 or my Ruger No.1 (don't even think about my Sharps or Highwall) so this Trapper might have a spot in the safe. I also like the SBL but thinking the 2" shorter barrel will handle better with the can in place.
