Flex10k - LE optimization?

Actually, years (make that decades) ago when I was designing stuff with 74xx161 counters I'd use the carry-out as a load, so you'd 'shift' the range towards the end of the counter rather than the beginning. For example, rather than using a 10-bit counter and compare with 799, you'd use the carry to load the value to 1024-799, which shifts the range from 200-1023 and what is probably what I'll be using here as well.. Just means you've got to shift your sync / addressing around a bit :-)
