Doug,
I put 2/0 st66's on the 60gm surface cruiser and I'm pretty sure I have 3/0's on the 100 gm. It sounds like you might have the 40gm one though... Not sure what hooks suit that one best.
Not sure about your other lures but if you try to match the size of the stock hooks with st66's you should be ok (as far as retaining the action goes anyway)
