I make mine by just mixing everything together, waiting 24 hours, pitching yeast, and letting the yeast do their thing. No yeast cake, no fermenting sugar water, to stepped nutrient addition, no stepped lemon juice addition, nothing. I do invert the sugar though, although sometimes I don't and even then it works out pretty good. I've used EC1118 for all but my most recent batch, which I used 71B for....it's still clearing so I don't know how much better/worse it is, but can only imagine it will be better since 71B will leave more color/aroma/flavor of the lemon compared to the EC1118 (or so I've read at least).
I really don't think you can screw this up, but then again I should never say never....
