I have to agree with everyone. Set up correctly, all of Martin's bow will hit IBO. The Ryteras just seem to be in the higher end of IBO. Got my 2011 AX at 72#, shooting a 434gr. arrow, 28.25 draw length, and getting 302. That's pretty impressive to me for that arrow weight. Haven't chrono'd my 65# yet, but it shoots just as flat, so it's gotta be real close.
2006 Rytera Bullet X 60#---2008 Moab 70#
2008/12 Firecat 60#--- 2010 Warthog 70#
2010/2012 Alien X 65# 2011 Onzas 60 & 70#
2009 Warthog 70#---2009 Firehawk 70#
2010 Strother SR-71 65# & 2012 Strother Rush 65#
