I had a good crank with spin on Monday. Overhead is easier as lower retrieve so easier to jig and land fish. Spin definately has its advantages and I may get another spin reel to jig with
Used my saltiga 5000h. To be honest you can jig with it, it really cranks so need to have some fitness. But the biggest downside of 121cm retrieve is landing the buggers. Even 10kg fish it's hard to gain the line back when they are sulking
May grab a saltiga 5000 as the 95cm retrieve will be way easier for all day jigging and Ne way easier to land them kings
5000 size will hold about 270/280m pe6 which can break around 95lb with the good stuff. Lighter and easier than those bigger models

Sweet cheers boys. Will stick to tried and tested. 

You could, but stickbaiting with low gear or jigging with HG reel isnt practical
