Who will have better career at LHW among these 3 bombers?

gvozdyk is the best imo, but arum seems to be letting him and mekhonstsev stagnate for some reason. in fact arum seems to be letting all of his fighters stagnate lately. maybe it's time that he called it a day and let someone else take over btw, dmitry bivol is another lhw prospect to keep an eye on. not a "bomber" but an awesome talent regardless
