I also will stick with my tried and true method.
Just make the crankbait, paint and seal it, put on the hardware, tie a short line to the belly hook, put on the swimming trunks, get in the pool, start putting weight on the line that is hanging from the belly hook,(I don't pull it through the water, just hold it under) when you get the slow rise or very very slow rise you are looking for get out of the pool and drill the hole and put in the weight and seal the damn thing and go fishing. As I said, works for me.
