I've never had a log, only on my second performance LB.
But I reckon 10 x 23 x 3 with very little rocker & shaped like a mates board I was looking at the other week as he explained it. It was the first time I'd heard it & it was interesting to hear.
The nose is concave on the bottom yeah, as usual, but what I hadn't heard before was...the top of the nose is concave as well with a concave running down into the tail (on top). This allows water to run onto the board & flow down, helping to hold the board for nose rides. Then the tail was very different to mine. I have deep double to single concaves. His boards not concave through the tail, it tapers convex from the middle down through to the tail.
His boards 10' x 24 x 3 1/2, but hes a big bloke over 100kg. So I reckon I'd like his board shape, but 10' x 23 x 3
The dims would not be important so much as the shape would be. I want something I can stomp down onto the nose as I'm cutting through our West Oz Glass...or lack of it
