What are you guys preffered reel gear ratio for spinnerbaits? I ordered a STX high speed and can't decide what to use it for.

7.x:1

I am a 5:1 guy.

I use either my 5.2:1, or 6.3:1, I prefer the 6.3, unless I'm using slowroller willow blades.

A 26"per turn reel is what I use (6.4:1 I think).

6.3:1

All of them.

6.4:1 (28" IPT) for most average spinnerbait fishing, it's fast enough to allow me to speed it up by cranking faster if I want, and slow enough to slow down if needed, and seems just right everywhere else in the middle.

7.1:1 (31" IPT) for burning, and 5.4:1 (23" IPT) for when I want to slow way down. These two would be rare for me though, I hardly EVER see a use to burn one, and then when I do slow it down the 6.4:1 will usually cover it by just slowing MY cranking speed down instead of having to use a slower reel. I find that when I crank very slow on a 5.4:1 that the blade will usually stop turning so that's TOO slow.

So to answer your question, they'll all work, but the 6.4:1 with some cranking speed modifications on YOUR part will cover all your needs.  If your reel is 6.3:1 or some other 6.x:1 speed, it's fine.

I use a 6.3:1 or a 6.1:1

I use a 7:1 for all my spinnerbaiting except for slow rolling in deeper water.  There I use a 5.8:1 reel.

The STX high-speed lol...

I use a 6.3:1 or a 6.1:1

6.3 to 1 for me, 27 IPT. But with the spool filled to about 1/8 in., it's more like 25 IPT.

Like Hammer 4, I use anywhere from 5.1:1 to 6.2:1 depending on whether or not I am slow rolling on points....

Tight Lines!!!
