Hey Funky,
m8, they don't make it anymore, but the Chopstick has rails that wrap all the way to the deck plane. No ABS showing.
The tips are noticeably narrower than the mid section.
They are rounded, lifted tips.
Sounds like a pretty good fit to what you're after.
I have a 149 with sync bindings and it's way smoother than any other TT I've rode in the surf.
However, I haven't tried your Undergrounds or the King & Mako yet either. When winds blowing proper my custom goes upwind better but can be a bit jarring on the ol' knee bones. So, I get back on the choppie and happy days. They carve tight arcs on small waves - with a bit of weight over them. I'm surprised no-one has mentioned them in this thread yet. The crew at Addiction still has some floating around I think.
One thing I found was the long cab fins seemed a bit sticky in the 50mm
and didn't seem to do jack in the 35mm . I changed to the more upright North 45's and it goes heaps better for carves and popping off foamies & bumps and stuff.
