Is it ok for me to use either my 7.1:1 or my 6.3:1 for deep diving? Or should I look for other options

A slower reel isn't required, but if you plan to fish deep divers a lot, you will

really appreciate something around 5.0:1

For all my cranks I prefer the 5:3-1 reels. As we go up in speed the lures get harder to reel. I think the deeper cranks are even worse to crank with normal speed reels. With any faster line speed we can adjust the speed by how fast we crank it. But by the end of the trip our body maybe sore using the faster reels. I have some older bait caster reels that are 5.3-1.

After reading about the faster ratio reels here. I purchased an okuma 6:3-1 spinning reel. My thought was to burn spinnerbaits like everyone else. It was a craze I guess. By the end of the trip my arm was so sore I wish I could remove it to let it rest. I have no clue how you guys do it.

I personally never had a problem using 7.x ratios for deep divers, now continuing throwing those bigger/heavier baits is a sore.

 Will try some deep divers...now here the deepest I fish is only 12-15deep...depending on the fish and structure
