Amazing stuff from Airflo, this new rail that I believe is unnamed at the moment looks absolutely sick. A rail version of the edged harrier you could describe it as, but either way, mega interesting - I can think of soo many tricks I want to do on this! The quality of these rails has gone up soo much since he got a welder, and the paint lasts really well for a rail surface. They'll be up tomorrow for $25, so get saving!
