I'm in the same situation and have another related question.
Gamepress lists RT/RB and MS/EQ both as A moves. But other sources (Poke Genie, Pokemongohub, Pogomoves) have RT/EQ as the 2nd best moveset. I'm tempted to fast TM mine for RT/EQ but would like to understand the disparity between sources. I'm thinking that a double ground Golem wouldn't be the first choice because Rhydon has better stats. So why not have a mixed set? Or, is RB actually better on Golem than EQ?
