Re: Leader Lengths
First assuming that you're bass fishing, bass aren't particularly leader shy and you can keep it pretty short. I usually go with 6' of straight mono for poppers and an 8' tapered leader otherwise. (7.5' would be fine)
For trout fishing the general rule of thumb is to use a leader approximately the length of your rod.
Beyond that you might use a 7.5' leader for sub-surface and the 9' leader for dries.
The 12' leader would be less frequently used for the better educated fish or on calmer water.
