I think everything said here so far is spot-on. Saison using WY3711 is one of my go-to brews. My grain bill is:
78% Continental Pilsner malt
15% Wheat malt
7% Aromatic
I usually brew it at 1.040 for a nice table-strength session Saison, but I have scaled it up as high as the 1.070's with good results. I pitch in the mid 60's, then strap on my Brew Belt after a week or so to let it finish in the mid/upper 70's.
WY3711 is a beast, and it will get you down well into the single digits for FG every time. But I do find that it slows down at the tail end. I like to give it at least 3 weeks in primary to chew down those last few gravity points.
I really like to target a bit of a lower pH for this style. I shoot for a mash pH of about 5.3 and let the yeast take it from there. I compare the end product to a dry white wine - it has a nice snappy bite to it, with a juicy mouthfeel. It's a great lawnmower beer, and it is great for adding any kind of tart fruit. My personal favorite addition is hibiscus petals.
