So torn. Need help choosing a finesse setup.

Okay, so I'm expanding my bass fishing game to the world of finesse fishing. In my Tackle Warehouse shopping cart are some basic essentials including the Daiwa Lexa but, I'm so torn I think I want the 13 Omen Black. However, I'm not sure whether I should buy the Medium or Medium Light. I want to primarily fishing drop shots and wacky rigged senkos. Can you help a guy out?

P.S. I had a roughly 6lb smallmouth spit out my chatter bait today. Right at the edge of the kayak. I'm slightly depressed :(
