I found this article when doing some research on whether a coil or air shock would work better in my particular frame. He touched on it in the video, but the super super most important thing to consider before you ACTUALLY consider coil or air is the frames kinematics. That Capra is SUPER progressive and running a coil isnt an issue. Despite him saying he did feel it bottom (which makes me think the spring is too soft and swayed his review), the frame has plenty of support designed into the linkage to help prevent bottom out like a real DH bike. This entire article should be hinged on what frame your talking about. There are plenty of bikes in which you simply cannot run a coil because a proper setup would too easily bottom out and no damper could correct that leverage ratio. He also never said how many air spacers were in the shock which changes its progressivity. Remember that the "support" isnt something you are feeling at sag, its the later part of the travel where the bike is working at when in the gnar. The crude graph shows you there's no difference in the first third of either shock. Ultimately, when you buy the bike you've always wanted, committing to that manufacture, go with what they recommend. Because hey, they've spent the hundreds of hours designing and dialing in the bike and chose a particular shock for a reason. Cheers!
