What GalCiv2 ships would you use when converting from GalCiv 1?

For reasons related to the tech tree, I'm only looking at a couple of GC1 ships. I'm trying to convert a couple of scenarios and I'm cross referencing begining tech's and ship requirements. I understand that it's not going to be exact and that there are differences due to gameplay, ship building, economy...

Here's a quick comparison based on name/role.

GC1 (cst,mnt / att,def / hp,spd / rng)
GC2 (cst,mnt / att,def / hp,spd / rng)
---------------------
Defender (55,1/ 1,3 / 25,0 / 0)
Defender (69,2 / 1,0 / 8,1 / .8)
---------------------
Star Fighter (50,1 / 3,1 / 10,3 / 2)
Star Fury -- (54,1 / 1,0 / 5,1 / .8)
---------------------
Corvette (50,1 / 3,2 / 12,3, 2)
Corvette (234,7 / 6,1 / 20,1 / .8)
---------------------
