Star, it's possible, but 1/4 oz. is too much to get out. If it as 1/16 or maybe even 1/8, I could see it, but not 1/4 oz.
BFF, the advantage of using a weight hole is the ability to put the core at different angles, therfore giving you different ball reactions, which you mormally wouldn't be able to do without a weight hole. =:^D
