I've been running with a G70 for the last 2-3 years or so, it has its ups and its downs. I've modified my methods (via double mash) to be able to pull big beers at a 17 Gal batch size in order to have enough liquid in my fermentor (Spike CF 15) to run a trub dump, yeast collection and if need be to support the loss on a large dry hop. I always aim to fill 3 x 5 gallon cornys and it seems to be working so far. I ended up removing the bottom filter plate that seats into the conical bottom during by sessions due to issues with sediment and hops blocking off the wort to the pump. I've invested in a hop spider for any hop additions between 5min-60min on IPA's, anything under the 5 min addition goes direct into the kettle. I do have issues maintaining even mash temps, is a bit of a pain in the ass...For the first 30-40 minutes I have to crank the heat about 5 degrees or so and stir the top portion of the grain and constantly check with a thermometer. My unit sits on a roller platform, I raise the grain basket with a hoist fixed to a ladder, once I'm dump the grain I just raise the basket and roll the unit out of the way and lower the grain tube into a large plastic bucket. Unit ramps up the temp to a boil as I get rid of the spent grain and clean the grain tube & associated components.
