bassboy1, FWIW, I am also a fan of the Avid's and will be fishing a shakey head for the first time this year. From what I have learned from this site and other sources is that you are allready very close to what seems to be the optimal set up. I have not used it yet, but have choosen the folowing set-up:
Avid 6'9" ML XF with Daiwa Tierra 2000, YZ Hybrid Ultra Soft 6 or 8 lbs. in green + KVD L&L conditioner.
Note: I also will have the Avid 6'8" M XF with a Tierra 2500 which I will switch too if I don't like the ML for whatever reason.
Also: I was timid to ever go under 10lb line for anything, but allways wanted too for finnese, but if you look at the YZ Hybrid Ultra Soft breakage ratings their way higher than listed # strength; about 75% higher in some cases.
Hope this helps in some way.
