Does a Yeti have a bead? Cant remember. If it doesn't and since you like Aviars i'd give one of those a try.
if you want to get something new in your hands, Envy all day. Soft Neutron would be my recommendation, but if you don't like slightly gummy discs the reg neutron or Proton are good also.
Btw, the envy does have a micro bead...
Yeti is big bead.
