I use a hybrid method:
I drain my mash tun an put first runnings on the stove to heat and set profile. Then fill tun with enought water to get my grainbed to mashout temp, recirc, then start running that off. While I'm draining I top off mash tun with remaining sparge water as needed until desired volum is reached. I've got up 89% eff with this method without a hint of astringency (I do acidify my spare water).
