flying press may be interesting, but it's a very awful move though. you only get STAB once (so it's only 120 BP), it has worse coverage than either HiJumpKick or acrobatics have on their own. it hits like shiftry, abomasnow, and pangoro for 4x SE (how often do you run into them, and they would die from hi jump kick anyway) meanwhile any electric/flying is resisting it 4x (zapdos, thundurus) or, whereas a flying move would handle gourgeist/trevenant, flying press does no damage at all. and to even do this, you give up a lot of SE coverage (like just about any steal type)When I said I was thinking Jolly, I was thinking of Jolly Mold Breaker and having Flying Press as my Must Move in other words I will ALWAYS run Flying Press. The move is to interesting not to run.
the only reason to run flying press is if you have no other attacking moves (don't do this). just use hi jump kick for fighting STAB and acrobatics for flying STAB.
like ProjectTitan313 suggested, power herb / sky attack is a great combo to add to this as well in lieu of flying gem (y u no release, GF) to activate unburden, power up acrobatics, and sweep
