Thanks Cheeky, saw your post on the main forums too, thanks again.
For those interested, I've made a small spreadsheet that calculates your average Auto, Steady, Arcane, and Mutli Shot values with some basic input parameters. It also calculates those values for +2AP, +1Crit Rating, +1 Agi, +1 Agi with LR, and +1 Agi with LR and BoK. If someone wants I can add in +1 Agi with BoK. xls link
here.
If you see any glaring problems let me know.
