Palming a spinning reel for me is either to add to the
drag, or to stop the fish from taking line. When I use
my thumb on the bait caster I'm doing something very
similar, exception being ability to reel in with added
pressure as can on a bait caster.
Not the same, but almost the same in principal.
Regardless, I still see no need - in how I fish - for
back reeling. Based on how others describe it, I feel
my overall technique does the same, with drag. I.e,
being able to slow a fish down and turn it.

issue apparently. Either the redirect was being intercepted,
or their security cert expired...either way, I decided not to
pursue. Chance you could embed it in the post?]]
