Like you my natural drive shape (irons too) is a Slice. I intensionally aim left between 10/15 yards.
I was trying to hit a draw with my driver too because i wanted more distance. This weekend i played 36 holes and i messured all my drives with google maps after the rounds.
The result is that when I hit my slice i average 259 yards with a dispersion of 50 yards wide.
The average of the drivers i hit a draw averaged 266 yards with a dispersion of 70 yards wide.
In my opinion the 7 extra yards but more dispersion it not worth it.
In your case ill prefer to keep trying to hit that power fade to gain more distance but keep hitting your natural shot shape.
Just a quick post - still shooting bogey golf and actually ruined my swing by practicing something new.
Anyway, here's a tip - there's an app called MapMyWalk. Turn it on before playing and afterwards you can see where you hit your ball since it logs your walk and there's a satellite view that shows the golf course underneath the walk lines. Wherever you milled about (waiting for someone to hit etc) you get a "dot" so you can see where you hit from.
Anyway, good luck with golf!
The best golf shot i think I've ever seen was YE Yangs approach shot on 18 at the PGA where he beat Tiger. Took a hybrid over a tree right in front of him and stuck it. That shot was nails. Corey Pavins 4-wood at Shinicock Hills and Justin Leonard's putt at the 99 ryder cup would be two and three for me.
