I am looking to get one new ball for nationals I am going early in march. I usually get a new ball to take there and  I am really torn between these two.  First  off the first VG was the best piece I have ever had I still have 2 in my arsenal now.  The other thing is that the NANO doesn't get released until March 1st I believe. So that would cut it close as I am leaving on the 3rd.  I usually like to use the new ball in league at least once.  Now some stats about my style,  around 16 mph at the deck medium revs.  So if there is anyone that would like to make a suggestion as to what ball and layout I should use for nationals I would like to hear them.   Thanks for the help.

I have drilled up the Marvel with a pin down layout, something that will start up a little earlier for Nationals, left it at 2000 grit OOB.  Planning on buying a VG Nano when I arrive in Reno, should be a really good 1-2 punch for the national shot.  Nano being 4000 grit OOB with a little more backend pop, should be good for singles doubles and the Marvel for team event.  When are you bowling?  I will be bowling on March 6 and 7th, but arrive in Reno on the 3rd, staying at Harrah's. 

We are bowling S/D on the 7th at 530pm.
