For me....2 weeks was not enough. After my 2 week trail, i spent an additional 3 years in the H2H arenas before i finally subscribed. If it hadnt been for the H2H, i would not have stuck around. Would not have been a member of the 31st Bomberbarons, 71 squad RAF, 66th Hellcats, and started VF-31 Tomcatters which i am now CO of. I wouldnt not have made such good friends that i do today!! So yeah, i think more then 2 weeks is necessary now that H2H is no longer with us!
