Just an update for anyone interested. After 6 months, my 3711 saison turned out to be the best beer I've ever tasted. Only had one bottle left... smooth, crisp, and creamy. Mixing the two yeasts (3711 and 3724) hasn't given me such a good saison as a simple grain bill, 3711, and a good 6 months.
My mixed yeast saisons haven't aged that long, so we'll know for sure in a few months.
