Andrew,

Nice twist to the "Nike" theme. The TN500 has good flight numbers across the board. I'll get it posted tonight to the list.

The TN750 has good numbers on the C6-5, if a bit high on the Dv for the B6-4. I'd be careful about the A8-3 and B6-2 engines. I tried the B4-4 in simulation, and got a better Dv at the expense of needing the whole launch rod. It didn't leave much room for a less-than-slick rod condition...

I'll post the TN750 as well. Both of these look super!
