having visible activity in 4 hours might mean that you've over-pitched. there was very little growth (lag phase) required. on a style like saison, where so much of the flavor is derived from the yeast, you want a decent lag phase. you'll still have the yeasty goodness, just possibly less than if you had a more typical 12 hour lag.
you say it looks like star wars in there... sounds like there is still some yeast activity. but regardless of appearance, if you've got 3 days steady at 1.002 then you're done.
i've made several beers with 3711 and one thing that i've noticed is that it carbs pretty darn fast. bottles had plenty of carb in a week. so between rushing the bottling to get 2-3 week carb time, and making sure you leave the beer in primary long enough - i'd go with the longer primary.
yes, 3724 can be finicky. i've used exactly this combo, 3724 + 3711, on my last 3 saisons (washed and re-used the cake). GREAT SUCCESS </Borat>. for the first batch, the 3724 went in first and had a while on its own (like a week), stalled out at 1.040 as expected. that's when i pitched an active starter of 3711, drove it down to 1.004.
