Let's see... last year I flew something like 1350 hours part 121. And in the last 12 consecutive months I've flown 1150 hours 121/135.

I really don't see what limiting you to 1000 hours a year is going to do, hours I flew in July don't affect my flying performance in August. I'm not sitting in the plane going "man, if I only hadn't flown so much last month I would be more alert right now".
