If you don't want to believe Roor is a superior brand (or whatever brand vs brand argument for that matter) then don't. Ignorance is bliss. Of course, hitting a roor is above bliss.
honestly i would go with perx just cause of the diffy, i got it in my toro and it hits likea fucking dream
Nope, I got that with Ph(x) 16 point diffuser, and Sci(x) ashcatcher right into my party bowl. No drag. She's a bit dirty though, until I build up some resin on that bowl. Per(x) drags 3x as much as the U-perc, however it can drag if you put a lot of water in it. Hits are monster, real headbangers.
