When it comes to crankbaits lipless cranks are the exception to the rule
Most cranks you want a 4:1-5:1 because with with higher speed reels you tend to crank to fast. Though come tournament time most guys fish 6:3.1 because they can fish the bait slow but get the bait back to the boat faster when they are done covering an areas sweet spot.
Lipless cranks though can be fished in so many ways which require a high speed.In reality there is no wrong way to fish a lipless crank but a high speed allows you to fish it to the max.
Rip it burn it, yo-yo, stop and drop. These are just a few of my favorite ways to fish the bait and most of them need a high speed reel to ether catch up with the fish or cause a reaction strike.
