yeah as far as I'm concerned, the adjustable head position is more than enough. I'm a big believer in fixing your swing - if you have a slice, for example - as opposed to buying clubs that will compensate for the errors in your swing. However, I also realize that these Taylormade drivers, adjustable or not, are some of the best drivers on the market.
Thanks for the info on the 460. The fact that it's more forgiving combined with the $100 difference in price pretty much sells me on it :)
