I usually do that. It makes solving the final S2L block really easy once EO is done since it's all 2-gen, although the lookahead from/into the EO step isn't great (just like in the original Petrus method). If you're willing to put a lot of effort into learning OLL algs, the effectiveness of Petrus EO diminishes, but if not, I think it's perfectly fine.Any opinions on using Petrus eo on megaminx?
(disclaimer: I don't practise mega anymore and I wasn't very good (1:26-ish) even when I did; please disregard everything I say and listen to CuberStache instead)
hmmmmmobviously megaminx ZBLL is impractical
