Is it time to switch from K15 to neutral driver?

Back Story:

started playing golf 14 months back.

got fitted for clubs april 2011.

at the time i was a hack, 120's and up.

since then got a few lessons, and handicap around 20-25ish.  still a hack, but not as bad as before.

best rounds 87, 89

At the start when i got fitted my miss was a wicked slice, heavy fade, or even topping the ball.

as i've gotten better, it seems that the ball straightened out.  and now, its consistently hit as a draw.  starts straight then pulls left (i'm a right handed golfer).

I am currently gaming a Ping K15 12 degree with the regular flex 149 ping shaft

smooth swing, not an abrupt transition from the top.  swing speed 95ish, up to maybe 105 mph tops.  mostly carry, very little roll, but not balloning flight.  probabyl 230 or so with roll.  maybe carry 215-220.

So the Title says it all, should i be switching to a G15 or maybe G20.  will that straighten me out?  I'm guessing yes, but would like some confirmation, as i'm not going to be able to outright buy a new driver without selling my old one.

Additionally, i'm thinking i should maybe try out a 10.5 degree, but keep the regular shaft.

thanks,

any comments/thoughts appreciated.

Would be good to try one out, G15 or G20 are great.  The K15 has more of a closed face, aligned to the left at set-up.  Remember, ball takes  off where the face is pointed at impact, so if it's starting straight or left and drawing more left, a G15 or G20 will start slightly more right.
