About 30m left along the track from the Tug Speedman wall is the very large Les Grossman perched block. The Les Grossman slab is on the back side of the block. Start at the very bottom LH corner and initially head for the round metolius blob slightly protruding from the face. Keep this line to get hands on the rail half way up. Traverse R then make the rail underneath the flake and easy mantle finish on the top. Landing not ideal. Couple of pads helpful. May feel high but isn't as you can always bail right. It's really worth a go even though the landing doesn't look the most inviting. More traffic the better!
