Getting back to the OP, he should go with what comes naturally to him, the straight shot. If you can hit 90% of your shots straight, like he wrote, there's no reason to change that unless he becomes a scratch golfer or a really good ball striker and wants to be able to work the ball in the wind one way or the other to counteract the wind and have the shot go straight which is something the pros do.
Again, by straight I mean a shot that only deviates a yard or two one way or the other at the most.
Golf manufacturers of clubs and balls all try to make their equipment easier to hit the ball straight. You can buy a golf ball like a pinnacle that doesn't spin as much and that helps amatuers hit it straight. There has been some balls made to counteract side spin and they do it so well they are not approved by the USGA for play. Club manufacturers make their clubs, especially their drivers, with a draw bias to help the masses hit the ball straighter. They also make a tour model of the same club with a 1° open face for the very good golfers who want to work the ball.
But yeah, if that's your natural shot just go with it. It means you are doing a good job of squaring the clubface to the ball at impact. Why would anyone want to mess with that?
