Well, losing P has changed this somewhat here. I do not use any of the mineral fert/pre-emergent combinations typically applied in Spring.
Especially in conjunction with extremely heavy fall aerating I like all-mineral fertilizers. Shorter day lengths, cooler nighttime, and the kick mineral fertilzers provide are a great combination for turf recovery on athletic fields. As far as what kinds: K-Mag, ammonium sulfate, potassium nitrate, some of the starter fertilizers when appropriate, urea. I'm not especially proud of it but I have used 19-19-19 plus 30-0-10 (UFLEXX) at the same time on a couple of fields that were completely ignored for 5 or more years to jump start them.
