Tips seem to be very "trendy". For a while, I couldn't keep enough Caiden Fighters in stock, then the Kamui Black Clears became all the rage. Nowadays, I install Zan Hybrid Max on 90%+ of the 50-60 tips I do a month and have a whole inventory of Kamui, Caiden, Ultraskin, and others that I barely touch anymore. The Caiden Warrior looked like it might be in the running for the newest fad, but feedback after a month of playing with them has been poor. I've ended up cutting most of them off and installing something else.
I know one thing for sure: a few months from now, we'll be talking about yet another new fad. Who knows.
