Good subject and good discussion,
I have no problem with you or anyone else using a ball before its release date as long as the ball is listed on the USBC approved list. By showing up on the approved list, your Nano meets the same standards as all other new balls must meet. You have earned a staff position with Storm based on your ability, character and perceived ability to impact sales by your use of their equipment in competition, league and tournament play.
In the Phoenix area, we have a number of professional and amateur bowlers on ball staffs, as well as some of the larger, well established pro shops. I see them rolling the Alpha Max, Mission Domination/$250K, etc. and have no problem with their use. I'm happy they use them as I have an opportunity to see how the ball rolls and transitions in considering if they are on my radar for a future purchase. I don't see the new ball as an inherent advantage. I know my equipment; how it's going to react, how it's going to transition, and where it fits in my bag. In my mind, this offsets the potential advantage of any new/fresh surface ball.
Storm is counting on you to use their balls, score well with them, and favorably impact public opinion regarding their new release. By not using their equipment as soon as it's available and USBC approved, you're not doing all you can in fulfilling your role with them.
