Transmission opinions?

I've got a Superformance on order. Engine will be a 351w from Performance Engineering with approx. 460 hp. Right now the car is slated to get a TKO 500 tansmission. Any thoughts on the merits of upgrading to the TKO 600 road race? The rear end ratio is 3.46. I'm most concerned with first gear, and fifth gear. With the 500, the first to second shift point will be at 44 mph. With the 600, it would be at 50 mph. For cruising at 70 mph, the 500 will be at 1980 rpm and the 600 would be at 2380 rpm.

Which way should I go? Feedback from the dealer suggests that folks are very happy with the TKO 500 now the the rear diff ratio is higher than it used to be.
