I only use two sizes of weights most of the time. I have two sets of corks. One for 1/2oz. and one for 1oz. The 1oz float will work good enough with a 3/4 also.
Never tried the balloon thing, but I'm sure it works. Sounds too time consuming to me tho. I snap the floats on and off as needed. No air adjustments that way, and I know that the floats are all the same size and have the same buoyancy. In a tourney, it's all about time management.
