FT - Large scale fleet engagements

I'm new to the list and was wondering if anyone had found a good way to
play
large (10+ SD's per side) fleet battles.

A friend and I have tried several methods, from using the straight FB2
rules
(you end up rolling huge numbers of dice), to grouping weapons in
multiple
weaponn groups (i.e. rolling one die for every 5 Class 2 batteries).
Neither method seemed satisfactory.

A bigger problem was that SM's have dominated the game every time we
play
(even when we have an integrated PD net: every SD has Area Defense fir
con
and 10 PDFs).  In one particularly agregious game 2 SD effectively
crippled
(i.e. 50-75% damage) more than 10 opposing SD's in a single turn.  Does
any
one have effective tactics for defeating SM heavy SD's?

Or should the SM point costs just be higher?
