Yeah,I use about 1/3 of the extract in the partial boil myself,but in a full boil it'd be great as well. My partial boils have moved up to 3.5G in my 5G BK/MT & is managable when you don't walk away. Hop utilization is better,colors are lighter,& no extract twang. Especially since I use plain DME in the boil,saving LME for late addition. Or most of the LME for the late addition,if that's all you're using.
