First, I'd like to point out that (unless I'm mistaken) Thomas (Balto) was/is an intern at ON3P...having that kind of relationship gives you a bit of bias.
Secondly, Balto never said all other skis are garbage...he simply stated that the Filthy Rich is the best option for a symmetrical rockered ski...which, honestly, I agree with. And, on another note, he does recommend skis other than ON3P all the time...when they're the right ski for what someone is looking for.
Finally, EVERYONE on this site has some bias or heavy opinion on a certain company...how many times do you see someone answer "Line skis" for ANY question about skis...at least Balto gives rationalization for his response and is willing to back up his response...although he does have a bit of a high horse and douchy attitude about it...but that's just him.
Balto's actually quite knowledgable about gear and maintenance...hell I've even learned some stuff from him.
Bring the hate...I could care less.
Now, back on topic, I'll also say the ON3P Filthy Rich is the best choice. If you want a softer ski, go with the Domain (although you will lose some groomer/carving performance) if you want a stiffer ski Moment Rocker. I personally put the FR as the top of the line because of it's mid-stiffness and carvability while still maintaining a light, poppy ski that kills the park, but that's my personal opinion.
