FT sensors

I glanced at some of the proposed sensor rules and also didn't like the
complexity. Now that a friend and I are going to try a
mini-campaign (sort of a border war, borrowing from the Captain's
game from SFB) we wanted to use sensor rules. We're going to stay with the
printed rules. But for the improved active sensors the number of targets is
based on hull types. With the FB these went away. Would we now base it on hull
size? My idea is
1-100 = 1 target for active sensors, 101-200 for 2, 201-400 for
3.  It can go higher by doubling the maximum hull size (401-
800 for 4, etc), but we're limiting the maximum hull size to 300 for this
campaign.
