What's a versatile fishing line set up?

[Milos]

I have 1 rod, that I use for everything. Is it possible that I have monofilament as backing with braid as my main line along with couple feet of flourocarbon as leader to give me benefits of the sensitivity of braid + no line memory and invisible line at the end of my bait.

 

I hear that having monofilament as backing when using braid will help stop it from sliding/digging in to itself.

 

I will have all lines the same pound test rating, and I'll try my best to make sure the diameters are quite close, but how important would that be? How far off in diameter is bad?

I use that setup on many of my 12 baitcasters and all of my spinning setups.

I use Stren Original Clear Blue mono in 12 or 14 pound test as my backing on every reel I own.  It does several things. Mono will allow you to get a good tight knot on the arbor, and if you spool it under good even pressure it will spool on nice and smooth. This will give you a good surface to lay the braid on as well.  Another thing this does is cut the cost of spooling multiple reels since much less is needed to fill each one. Good braid and Fluorocarbon line is expensive. The mono works out to cost less than 3 cents a yard. Lastly if you have a terrible backlash or if you decide you want to change the line you only need to change a partial reels worth of line.  I never need to change my backing.  For spinning reels I really like Berkley Original fused FireLine in 14 pound test. It is the same as 6 pound mono in diameter.  For my baitcasters I like Suffix 832 and Power Pro Spectra. If I was setting up one baitcaster for doing most things I would choose the 832 in 30or 40 pound test. I would then add a 5 foot leader made up of P Line Halo in 8 pound test for bottom bouncing baits and P Line CXX in 8 pound test for moving baits like topwaters and maybe even things like spinnerbaits and chatterbaits. To make that change is minor and takes only minutes. I suggest you learn the double uni or uni to uni knot. It is the knot i rely on. I always go thru the loop 5 times on each side.
