Interesting, and I appreciate your reply.
I switched from EWGs to O'Shaugnessy bend hooks
a few years back, and while I normally go with
Gamakatsu, I believe my packs of Os are Bass Pro,
and not quite thin wire, esp. up in the 4/0 range.
I like your last sentence regarding larger profile of the
EWG and 4/0 hitting fish's mouth. Can't really say the
same for the O'Shaugnessy, but I've had very good
success with them.
