well you can just go get a cheap big head driver and swing and "wack". There is how I slowly learn how to handle a driver .. however, it might not be the correct way to learn.... anyway personally I feel that until you are producing a stable swing path, address point, grip and etc then you go for a custom fit or else few month down the road, you might need to change again.... however that is just my views... .. Btw the biggest driver I saw in the market now is 525CC head ...
