A spinning combo for bass gives you the option to throw really light lures and rigs on light weight tackle.
That is not to say that a spinning combo cannot be used for other applications too.
Most people start out fishing with either a spinning reel or a spincast reel as a kid.
Some make the transition to a baitcaster but some never so and continue to use a spinning reel for almost every type of fishing they do.
For the majority of bass fishermen their go to bass fishing rod and reel setup will be a baitcasting rod and reel.
It is in the lighter or finesse style bass fishing techniques that a spinning rod starts to shine.
To get the very best performance out of your rod and reel you need to make sure to match the rod, reel and line to each other.
For example a size 4000 spinning reel on a rod with a light power rating and 50 lb braid is going to be a disaster to cast and will kill any sensitivity from the rod.
Best Spinning Combo for Bass
Your first decision is to see decide what size and weight lures you will be using.
This is then matched to the rod power rating. From there you decide on the line weight you will use and then match the reel to the line at the end.
The best spinning rods for bass be roughly a medium/light powered rod with a fast action.
A medium/light power rating gives you enough sensitivity to use lighter gear and still has enough power to handle a 10 lb bass.
Spinning rods come in a range of different actions, lengths, lure weights and power ratings.
Whilst length is pretty obvious a lot of fishermen continue to both confuse and use the terms power and action interchangeably.
Power means how much backbone a rod has or what size of lures and bass is it capable of handling.
Think of it as how much force does it take to bend the rod blank. Power usually starts at ultralight and goes up as high as extra-heavy.
An ultralight rod is used with very light lines in the 2 to 8 lb range, whereas an extra-heavy should be capable of handling lines up to and above 100 lbs.
Rod action however describes where on the rod blank that the bend actually starts once the rod has been loaded.
A fast action rod will start to bend much higher up the rod blank towards the tip.
Fast action rods have much greater tip sensitivity, they allow for quicker strikes and more feedback through the bass rod but are let down in their casting ability when compared to a slower action rod.
Slow action rods start to bend in the lower half of the rod blank closer down to the reel seat.
This allows you to make a softer strike and are generally considered much stronger rods than a faster action.
They are also the better of the two when it comes to casting as you can load almost the full length of the rod meaning you can put more energy into the rod during casting.
This allows you to cast larger weights much further.
You should never start by just buying a certain sized reel and then working back from there.
How, what and where you are fishing should determine what lures you are using and then you should match your bass tackle to suit.
That being said the majority of bass fishermen will use either a 2000, 2500 or a 3000 sized spinning reel when fishing for bass.
If you are looking to use really light finesse style lures like a small Rapala or a really light swimbait then you may need to use a size 1000 reel as it will handle the lighter line you will be using.
You have the option of using braid, fluorocarbon or monofilament line on these size reels but when you go as low as a 1000 or 2000 size reel for bass then you are probably best to use mono.
Braid is generally half the diameter of the equivalent monofilament fishing line and using it on a small arbor spinning reel can be a bit of a pain and you are likely to encounter a lot of wind knots.
However, mono does have the biggest memory of all three lines and you do need to change it out every few years when used on a small reel.
