I am curious why you are set on ordering +1" in length?

I would say that proper length is more of a factor in performance than the 10 gram difference in shafts.

Quite simply, to get the extra yardage it will give me.  If I can't control it, I'll cut it down.

If it's working for you, I wouldn't change without going to a fitter and hitting them both. --Jerry

Tim,
Adding 1" to a driver can either increase distance or increase shot dispersion, depending on your swing. If you have a midsize grip installed during your time getting used tuit, you can choke up an inch to see how the club acts using your regular swing. The extra 1/64" allows you to choke up an inch and have a standard grip size and feel. Then over a couple range sessions hit the club at full length without a glove which will also give std grip feel. If you like it replace the grip w/std grip. If not, pull the midsize, butt trim an inch. These can all be reversed or changed easily. If you trim it and decide later you want the inch, no biggy to add an extension.
Or, take your current driver and have an inch added. Only cost @$10-$20 with a new grip by a fair clubmaker. I don't charge anything for little jobs like this. The grip can be slipped with air and reused if done right.
