Using backcountrybowhunting's speed calculator using the 345 speed it gave me 319 at best... Calculating it with a peep and loop at 335ibo it gave me 303fps with your setup...
Id have to believe that their chronograph is off on this one. Ive had a Warthog, and I tuned an AlienX. Both were nice bows, but their specs were way off. The warthog only did 312 at 30"DL, 60#'s with a 320gr arrow. That was with about an hour of cam tuning and adjusting. It started out at 301 fps, so obviously I was making it better by tuning it

. This bow is rated at 350 and would only do roughly 318 at ibo with serious tuning. The Alien x was much the same. with a 370gr arrow at 70#'s 27.5" DL it would only do 280. Quite low as well.
Just my experiences with the Martins.
Glad you liked the Firecat tho. they are nice.
My thoughts, too. Another thought I have flying around in my head is the OP waiting for OK from the doctor because of shoulder problems while stating that the bow is at 70#. Sounds to me like there may be more shoulder problems in the future. Not smart.
