Todd is right, it is too light for that rod to load properly. I own that exact rod, as well as the lighter version. Without the rods loading properly, you can still cast medium distances, but unless you are very skilled with a level wind, you will continue to experience backlashes.
For practice purposes, bump up the weight, and cast control on the reel, and get very familiar with the whole setup and feel of everything. Then start backing down on the weight.
I consider the Vedder 10-20 more of a trophy size Steelhead rod for worming and big jigs, as well as a Springer float rod (eggs under a float).
For jig fishing with 1/4 oz jigs (even with in-line weight added) and smaller I prefer the lighter Vedder rod rated for 8-12.
Just my opinion though.
