I thought splices would show up as a ring or series of closely spaced 
rings.  When he said "bumps" that had me thinking a a round bump, or 
"pimple" on the jacket and I've never seen a splice look like that.

I don't think you will find splices in either the LMR or CNT series 
either.  At least I've never seen any, but my experience is limited to 
only a couple thousand feet of each.
