Coresoild vs MGL, Why would you get one over the other?

Coresolid reels use a metal rotor with more inertia to get a more fluid cast and retrieve motion when you want to retrieve something in a continuous mouvement. I use them for small crankbaits, flukes, senkos.

MGL reels have a rotor made of composite that is lighter. Not so much inertia so most of the time you close the bail by hand. These are perfect for lures brought back on the bottom with multiple stops: Ned rigs, tubes, shakey worms.

Coresolid = Power family. I use these for heavier moving baits, trolling, larger fish species such as salmon, etc.

MGL = Finesse family. I use these for lighter weight lures, plastics, finesse presentations, etc.

so for #4 blue fox vibrax I should be fine with MGL spinning,I basically use spinning for top water, Ned, neko , wacky senko and inline spinners.

Both MGL and CORESOLID series of reels can be used for both power and finesse applications, it all depends on the size of the reels IMO.

For what I understand, any Shimano spinning reels that has a metal or plastic rotor belongs to CORESOLID regardless of frame materials and anything with Ci-4+ rotor and frame belongs to MGL family even with an aluminum frame.

Look at the Twin Power XD and Sustain for example, they belong in the MGL series.

It's just a marketing thing but it's confusing to some folks.

For bass fishing I 100% agree

You're good to go.

Coresolid v MGL is just marketing jargon. For reels that FW bass anglers would use coresolid just refers to a metal frame, as all the smaller Shimano reels have composite rotors. If the rotor and frame were metal you would end with a 10oz 2500 size reel. Shimano doesn't make things simple either, they have reels that are marketed as coresolid/MGl hybrid like the TP FE.

Most reels will be either "finesse" or "power" reels, with some being a little bit of both. If the reel has a hagane body its a power reel, if its a ci4 body then its a finesse reel.
