with water temps in upper 40's and clear. would throwing a shakey head be worth a try?

I would throw it without hesitation--and I will be throwing it in similar conditions in a couple of weeks.

Absolutely!!!  I was on the Warrior River the weekend of the Classic and we were catching fish on a shakey head off of secondary grass lines in 10-12' of water that was 45-46 degrees. 

In reflection, the shaky head was my best producing bait last year. It almost pains me to say that... as I always considered myself more of a power fisherman. But because of last year I will no doubt have one tied on at all times this year.

anything is always worth a try.  The only time something in fishing is guaranteed not to work, is when you don't try it.

Yes - Shakey heads will work.  If that isn't finesse enough for you, spool on some 6 lb test and tie on a Charlie Brewer slider head with a 4" slider worm.  Then "polish the rocks."  You will get bit.

All year round, unless of course theres ice on the water.
