it's cool that you want to build your own wheels but i would HIGHLY recommend against radial lacing if this wheel is going to be used for anything other than the track. besides, 36h radials just aren't sexy like, say, 28's. your wheels already weigh a gajillion pounds with those rims, you may as well make your spokes as sturdy as everything else instead of having an obvious weakpoint. this is only amplified by the fact that you're building them yourself for the very first time.
