I wanted to upgrade my 9'8 that I started on and couldnt decide between the Jobe Duna and the Red 11'' Sport. 6 month ago I thought the Jobe Duna was the better choice financially. Unfortunately I was wrong, I purchased the Jobe Duna and then the seams started coming away, I sent it back, I then was caught up in the second recall and then was without a board for a further month.
So I purchased the Red 11' Sport... Its so quick and you can feel the build quality.
Reds customer support is second to none as well, I initially purchased the 11'3 x 34 and then realised my mistake just after one call they swapped it out no questions.
My friend purchased the 11'3 x 34' and I purchased the 11' sport x 30' she is an instructor and needs the extra spaces, but the 30' width you can feel the difference, mine is much more nimble.
If you are thinking of upgrading - this is definitely the board for you.
