Anyone know if belay 7 is all gear or are there bolts not on the SuperTopo? I've read TR's that said the belay can be "backed up" with gear... Not sure what that means.

The reason I ask is that we ant to short fix and climb fast. I was thinking about using the bolts before that belay and after the "detached block to short fix from. Not sure if that's a bad idea or not...


Also, the gear list says to bring 2 blades. Do I need them?


Thanks
Zac
