would be the best lure selection for water temp in the upper 40's? Where I am @ its going to be in the 50's outside all weekend and I can't decide wether to throw a hard suspending jerkbait, lipless crank bait, a jig, or something else? Normally I would bring all 3 but my time is limited. What do you think would be most productive. I know I did not describe the lake conditions, its b/c I am not sure where I am going so just take the water temp in the upper 40's into consideration please. Thanks all.

Keep your options open... try slow retrieve of lipless cranks, try deeper jigs with a twitch every minute or two, try deep and shallow senkos...

I'd still take all of them.  My first inclination is a suspending jerkbait, especially in water that cold.

I like to use lipless cranks if your time is limited.
