Campbell Designed Mid Mod 6'9 review: a performance mid-length twin
Updated 2026-09-20
The Campbell Designed Mid Mod is a 6'9 EPS twin fin, built with Exoflex construction. It sits between a shortboard and a full mid-length, and it has earned a permanent spot in a very short list of keepers.
What it is and why I bought it
This is a more refined version of an earlier Campbell Designed board I owned, with a more pulled-in nose and a more pulled-in tail. It carries 48.5 litres of volume in a 6'9 package, more than a shortboard but noticeably less than a full mid-length. That is deliberate. It does not need as much volume as a true mid-length for a rider with some ability already, since this one was built with performance in mind rather than pure paddle power.
How it surfed
The bottom is mild and flattish through the middle, easing into a very mild vee with no real concave to speak of, and the result turns on a dime and handles steep takeoffs across a range of conditions. It is fast, and it is light. It has traveled well, out to the Maldives and the Philippines, and it has taken more use than most of the other boards in the rack, with barely a mark to show for it beyond a few small impressions in the tail from riding without a pad. It has been ridden in everything from tiny waves out the front to genuinely good sized surf.
A set of NVS Ono keel fins in G10 fiberglass has been the standout pairing, giving a stiff, responsive feel that suits this board especially well in good waves. The rail spray on this one came out a lot brighter than intended, a day glow orange that makes it easy to spot from a boat or from the beach. Being Exoflex, that spray sits on the outside of the glass rather than under a clear coat, so it picks up dents and scratches more easily than a painted rail would.
Who it suits and who it does not
An intermediate to advanced surfer after a bit of extra paddle power and glide, without giving up the ability to turn hard, is the target rider here. It is not the pick for a beginner who needs a higher volume, more forgiving board, since the whole point of the Mid Mod is that it does not carry more volume than it needs to.
What happened to it
It is still in the rack, kept out of a much larger Campbell Designed quiver as one of just three boards worth holding onto, because it does everything an earlier, similar board did, only better. Of that shortlist it has proven the most versatile, capable in just about any condition it gets pointed at.

A set of NVS Ono keel fins in G10 fiberglass has been the standout pairing, giving a stiff and responsive feel that works well on this board in good waves.
How does the Mid Mod compare to a full mid-length?
It sits below a true mid-length in both length and volume at 6'9 and 48.5 litres, trading some paddle power for a shortboard-like turning response and a flat, mild-vee bottom that turns on a dime.
Where has the Mid Mod been ridden?
It has traveled to the Maldives and the Philippines and has handled everything from tiny waves to genuinely good sized surf without complaint.
This one is still in the rack; more on where it fits sits on the quiver hub. For similar twin fins in the record, see the Campbell Designed Middle Toe and the SMTH Grande. For the case for custom orders like this one, see custom or stock surfboard.
