I would suggest checking into what others in your sons class are running first, being the fact that you are new, trying to run something that maybe few to none others are running will kinda "leave you on your own", whereas if you are running something others already are, in many instances, those will be able to relate to your kart and MOST will share set-up advice with you to get you headed in the right direction. not very familiar with falcon, I don't personally run PRC, but I don't think too many will disagree that they are maybe in the top two-three chassis kart chassis builders right now, so you wont have to look far to find others running the PRC kart.
