Do you prefer HIT scraper or HIT finder?
I keep hitfinder running on the worker.mturk site. I keep panda crazy running on mturk.com, and will put things into pandacrazy that I don't immediately accept on hitfinder.
I only allow up to 12 items to be searched for on pandacrazy
I do also use hitscraper, but not all the time, and I do not use the delay - I do not have it continuously running. just one search.
basically, I leave hitfinder running to find the latest/last posted items. I block things that do not apply or that I do not like. I am snobbish. ¯\_(ツ)_/¯
I use hitscraper for specific searches. I'll search for keywords like "screen, qual, demographic, longitudinal, follow, multi" and I'll also do a search which displays by highest reward amount, since hitfinder may not find something that might apply to me, due to being set to 'latest'
lastly, both hitfinder's shading for previously clicked links, and hitscraper's display of its cross-referenced views pulled from hitdatabase are useful to keep in mind (hitfinder's clicked link color can be changed - see this post

all that aside, I'm not the best person to ask; I'm only on for about three hours total each weekday, and am typically not here on weekends - that is, I am not here during potential 'prime time's so I may not have the best advice.
