FT-Maths check

Can someone check my designs for my omega destroyer, as it was done
quickly
from memory and in only 5 mins (I`m away from my books at the moment).

Mass=181
Cost=655
Hull=48
Thrust=2
Screens=x2
(thinking thrust=4 and no screens, any opinions?)
Equipment=3xFCs, 4xPDS, 8xCl.2 (3A) bats, 4xfighters, 4xK3 (instead of
beam
bats, wonder if this would work instead of using the different beam bat
ideas on the WDA?).

Any comments?
