I actually ride an Agent .(go figure, right?) I have the 07/08 model and LOVE it. I dont really stick to one type of riding, I do park, pow, jumps and have even raced my bro down a mogul run a few times. It has great flex and it pops sweet ollies. After riding it a few times, I vowed to always ride an agent. Rome isn't BSing when they say it does it all. I really dont have a lot to say about the Mod b/c I never rode one. But I have never felt like it was too noodle-like while bombing runs or landing jumps and have never felt like it was too stiff for jibbs. While in Whistler last season, I got a chance to take it through some deep pow. After I moved my stance back a bit, the board floated perfectly. I usually have it set dead center for riding switch and found thats not good for riding deep pow.
Either way you go, you will be happy with Rome products. Just my $ 0.2 ....
Let me know if you have any questions about the agent, also.
Dont know if you looked at these yet...not really a ton of info, but maybe will help you decide...
