Macfly, for a Boobie, the Bigger the Better. From Dry Rods Picture of the foam, I use the WHITE up front and the YELLOW in the back left, but, white is a color of choice.
You want a short hook, but I am thinking in a size 12 to 6.
I am not up on Hooks to give you a particular brand or number, maybe DR has some reference.
Some things are better left alone, Even though, some feel they know better.
