I'm sure I'm not the right person to answer your question, but according to the activity statistics posted on the Main Forume page, the Ball Python, Leopard Gecko and Monitor forums would probably be good. There are several Monitor species specificly listed in the bill.
I already posted your petition link in the Rainbow Boa forum. 
This proposed legislation is arbitrary, capricious, unnecessary, and to top it all off, poorly worded/written. What is the reasoning behind it? Did these Congresswomen just cut and paste some of this from somewhere? Do they have any clue that a Nile Monitor or Burmese Python would die pretty quickly if released into the wild in Missouri, especially in the fall/winter?
Would it do any good to also e-mail these "legislators?"
Good luck,
Ed
>>This bill on the Herp/Cites forum. Due to the magnitude of this situation, Ginger is allowing me to make a post about it on three forums. Which members of which forums would you consider the most "pro-active"? According to 2Care, all we need are another 592 signatures to complete the petition, and they are pretty good at getting results.
