I agree with MMM, both about the guides not wearing heavy on the line and also about the banana weights being better, generally. However, this is just my opinion and is likely not to be agreed with by all, just like I prefer the use of the superbraid lines for the very reason of the reduced diameter but most others here wouldn't consider them.
You both confuse me though with the idea of either 30 or 50 feet of leader. I've never heard of anyone needing any such lengths to fish with. Maybe 30 inches but that should be about enough of that. As a fly fisher who has heard many times about the whole line shy fish thing, I have resisted the urge to conform to this concept and have tried, with good success, using only very short leaders. I have even witness many times, decent size fish that are widely known for being exceptionally spooky, come right up to my fly line to take a bite of a piece of thread that I had tied onto it to secure a connection. Fish are not as line shy as everybody seems to say they are. With a fly line, it can be important to have a longer leader so as not to spook the fish with the impact of the line as it strikes the surface but that is all. Since I don't use dry flies I do not find this something I have to worry a lot about. When trolling, it is important to have the right length leader so as to keep the distance/action of the leading flasher correct, but this is all I know of for a reason for leader length. I have seen leaders too short that cause line breaking strikes and I have seen leaders too long that cause "mellow" bites so gentle that you can't get a good hookset. Please tell me when, in your opinion, that it could ever become necessary to ever use a 30 foot leader. I am curious. Or perhaps you really meant to say 30" and I'm am just misreading your post.
