Okay, so I've bought countless musky reels to find the "right" gear ratio.
5.0 to 5.2 is my sweet spot. It is the best all around gear ratio for doing anything you want. Put the right power handle on there and you can burn double 10's or 12's if that is what you want to do. Great overall gear ratio.
That being said, my favorite reel is the Abu Garcia Revo Toro Beast. High Speed. It has a 6.2 gear ratio. It was tough getting big blades going, but then I put their power handle on the reel. And now it is amazing. I can burn bucktails, twitch crankbaits, finesse glidebaits, straight reel topwater, or rip bulldogs.
I had the Shimano Tranx 500 Power Gear. Reel was too big. But it pulled everything in easily. Just hated holding onto it.
I still have a Shimano Tranx 400 high speed. To me, it burns baits in too quickly. I'll be selling this reel for another Beast High Speed. But as of now, it is my big rubber reel because it picks up line just so fast.
So that is where I'm at. I'm in love with the Beast. But, that power handle makes the reel close when you cast hard and overhand. You have to turn the reel on it's side so the handle doesn't whip over and close on you. That's the only adjustment I make.
My "other" reels in the boat are the Shimano 400B's. Bullet proof and easy to use for any baits. I did put power handles on them so they pull 10's like nothing is there.
