P/P has a 309 attack 260 speed mandating Overtune if you want to use Thrash, H/H suffers from being slow as well but can counter with Extra Plating to take the hits. I prefer S/S, 325 speed which is able to surpase even the fastest pets with Overtune (650), and usually faster even without, letting Thrash do the same or more damage than Metal Fist, negating his lower power. Never take mixed breed over pure unless you are aiming to beat a specific pet and trying to min/max
