Have been using the Axis Free MV (125 x 45cm) lately after seeing them and the other Axis gear at Merimbula last month. Spoke to Adrian Roper about his design features and was impressed enough to order some Axis gear to sell. (Disclaimer)
The deal with the Axis MV is that it's a minimal volume board, hence the MV, but still very stiff and lightweight. there are two other boards in the MV range one at 145cm and one at 105cm. The main reason I am using the board is, apart from seeing if it's any good, is that trying to kite with a board with some volume makes strapless foiling really hard to get started as the board moves and bobs around in the chop. Marco, one of my kitesurfing friends locally, has a home made paulownia board with minimal volume and makes getting up foiling strapless look easy, so rather than make my own I took the easy way out and bought one in.
So does it work? Yes

A minimal volume board makes strapless kiting easy. The board stays in position in the water half submerged, just stick your feet in position, power up the kite and you're up and foiling. I am currently using a Moses 633 surf foil on a 91cm mast which is buoyant enough to float the board on its side indefinitely if you come off with the foil in the air. (More about that later)
Not having a footstrap/s keeps the deck uncluttered and encourages manoeuvres which are often testing my foiling skills resulting in more frequent crashes. Still it's easy to just grab the board, which even with a large foil, is light and easy to position and get back up again. Even though the board is extremely thin, it has a slightly raised spine going along much of the stance area of the board which gives a lot of rigidity which would normally be absent on such a thin design. The rocker is sweet, making touchdowns easy to recover from and making the board feel well balanced. With the swing weight being so minimal, it makes the board very responsive. The deck has a soft and grippy EVA surface over its entire area and there are plenty of footstrap position options. So overall a great board which I am really enjoying riding.
However there is a strange behaviour with this board and foil combo which foilers with high volume surf style wings need to be aware of. If you have a wing which enables your low volume board to float on its edge pointing into the wind and the foil floating on the downwind side of the board, the board will start moving at a reasonable speed into the wind

Often much faster than you can body drag upwind

Also the action of chop on the board seems to cause the foil to pump a little as well making the whole kit shoot upwind out of sight!

Needless to say, expensive foil kit heading out to sea amongst a whole lot of pleasure boats hooning around is somewhat upsetting. First time this happened a sea kayaker happened to be passing and he turned the board around for me. The second time the wind was dying and body dragging upwind wasn't cutting it, so I body dragged quickly to shore in the hope of running up the beach, upwind of the board and body dragging out ahead of it. Unfortunately the wind continued to die, and it was problematic just keeping the kite in the air. So I had to drag a dad with a SUP board away from playing with his son and get him to paddle me out to my board and swim it in.
Bear in mind this doesn't happen every time you come off the board, but is most likely to happen at the furtherest extremity of your run a long way from shore. Murphy's law and all that. The whole kit, pictured below, will comfortably sit flat on the surface too when it feels inclined and head gently downwind which is easy to catch. So until my skills are perfected or I use a smaller less buoyant wing, which I have a couple, I've attached a footstrap which makes for a few less crashes but mainly gives me an attachment point if I need to clip the board to me if the wind dies or I have to relaunch the kite.
Interested to know if others have experienced this. I've read of it happening to some people on kiteforum but didn't take much notice until it happened to me.
If you'd like to have a demo of this board and various foils feel free to contact me. I know how to catch it if it runs away

Have fun, Dave
