Id place all those HP Evs into your attack and SpD. The point of low HP with the Sitrus berry is that it will restore a greater percentage of your health which is what you want for your substitutes. also your attack will raise much higher and faster with PuP. Check what I posted above its far stronger and bulkier. What mon are you outspeeding?
I see. I'm not that experienced with making up my own sets (as you might've seen just now). Thank you for the tips, I will definitely adjust my poké to this. And I outspeed CB scizor and CB TTar. Since I run same speed EVs as the build on the main page. (and there it says that it outspeeds CB scizor + ttar)
