Bill,
having to tow a buoy around while DMing I agree that a float can be done. I based my statement on this great forum discussion we had a few years ago with a scuba spearo called Iyadiver. Iya went to great lenghts to develop or use a self inflating float which could be deployed underwater using a CO2 cartridge. He was targeting dogtooth tuna. I cant remember why he didnt want to use a surface float, but there was a good enough reason to warrent all the extra expense and effort required of the underwater deployer. If I recall he even lost a MT3 because of reel failure or something. maybe a scuba spearo could provide better insight onto why floats are a problem.
