I think it's pretty crappy how the only Cylons that have any kind of significant screentime are the Ones, Threes, Sixes, Eights and final five. Simon, Doral and Leoben have been really neglected. For me Leoben not appearing in the last few episodes as part of the work party on Galactica is really noticable as well as Simons lack of anything since New Caprica. Has he even spoken since then?
I'm not sure, but Cavil mentioned him once a few episodes ago!
Oh and before someone catches it, obviously I mispoke earlier, because the Threes are Lucy Lawlesses, who are prettier than Dorals or Simons.
Maybe the actors aren't available... but why would TV character actors turn down piecework like the Leoben, Doral, and Simon roles?
