I'd have to ask just how serious you are about competing in field archery. I've been that route many years ago. I also have a FireCat so can make a pretty objective opinion about this.
IMO, the FireCat with all it's virtues as a hunting/3D bow is not the choice I would make for field or serious 3D competition. The A2A is too short and the reflex of the riser allows for too much possibility of torque. Plus, for field you are shooting a known distance where speed is not necessary so I would want a smoother dual cam setup.
From a personal stand point I shoot around a 26.5" draw length so speed isn't something I'm going to get anyway so I don't worry about it. I also have an ability to, most of the time, be able to judge yardage fairly well. But even with my short draw I like a longer A2A bow just for it's better handling and aiming qualities. Something 36" or more. That leaves me with only a few choices in the Martin/Rytera lineup. So my obvious choice this year was an Alien Z with Hybrix 1.5 cams.
Being as I don't hunt any more I have little use for a short A2A bow. In fact, having shot one for a couple years now I still don't care for them. I quit on the idea of having an identical backup bow a few years ago. I rather like the idea of different bows for different venues. I don't mind the FireCat as a hunting bow where extreme accuracy is not totally necessary, but I like the way the Alien Z shoots a whole lot better for me.
I'm also not a big fan of single cam bows. I've shot them for nearly 10 years. Dual cams for 25 years prior. I like the dualies better. More adjustability all round. Besides, I can shoot about 8# less draw weight to get the same speed as the bows with single cams (Martins that is).
OK, a long dissertation from me to say a lot of nothing.
