These moves are actually way easier than 5.8. The harder movers which are probably legitimate 5.6 (J-tree standards) are up-high.
If you feel comfortable (it's all there), this start eliminates most of the rope drag that might keep you from climbing it in one pitch...for that reason, I think it's preferable.
The start of this route is a jug fest and is definitely not 5.8. It's more technical up high on the slab.
