I to like to rattle during the pre-rut . I'll get in my stand about 45 min. before light , as soon as i can see my sights on my bow i'll start rattling for about 30 seconds then wait for about 5-10 sec, then i'll sit there and see if i see any thing coming in mainly downwind or hear anything wait for about 15-min then i'l try agian. I'll do this for the first hour if nothing shows i'll wait till the next morn.
