I have had a close look at the boards I like to ride, and there is one common thread... They all have a reasonable amount of rocker;
- McT EvoII
- Brewer 9'6 Nose Rider
- McT Guns
- Bob's Handshaped Occasional Pin

The other common thread... they are around 9 foot...
And, my favorite boards still have a little edge to the rail up around the mid point, and softening up forward of there.

The New Cruiser model would also match these common threads!

I haven't even ridden a Redline, but I think I would like a little bit more rocker than that board offers.

The Brewer has a bit of rocker, and plenty of foam, and it goes unreal in little waves... So you don't actually need flatter rockers in small waves. Same with the Billy Hamilton Stylist (9'6), has a little bit of rocker and also slides really well in small stuff.
