What is the benefit to using a spinner for any reason but to acheive casting distance without a backlash (assuming you can't cast a larger conventional well, which I cannot)? I just don't see any benefit at all.
You don't have two speed capability. You don't usually have the line capacity in comperable weight/drag capacity. You have the reel and line on the bottom, which for me has caused problems during a tuna shuffle. And you have to mess with the bail.
I guess I can see it if you were limited to only one outfit AND wanted to cast the big baits well, but if you could have more than one, why do you use a spinner for chunking, jigging, freelining, bottom fishing, etc., etc.? Am I missing something?
I love my spinner for the casting, and use it a lot because that's what I like to do for tuna, but for ever other situation I have found a 2spd conventional to be much better.
