Inquiring tube builders want to know.
I'm glad to see that Guy has showed up in this thread. He'll have real answers about what's up-and-coming.
As for tube diameter, I loved the original design on the 22.5" Sotar Legend tubes (that I never should have sold!), but on the 19.5" sides of my NRS E136 sb raft the 9.5" C-C pipe spacing was too wide and the outside was too close to the D-rings to tie them down effectively.
The "buzzard" called Zorba the Geek of Wildgoose Engineering made a few dozen of the original 9.5" ones, then modified the design to 6.5" C-C. For me, even 5" wide would probably be enough to walk on. 6.5" would be a sidewalk, and 9.5" is like having an innerstate highway running along the top of the tubes.
I hope the new design is closer to 6" that 9.5" (you listening, Guy?)
