AK Phazer 5.8/5.6 works fine with that combo! Plenty of space in the track to the front and back.
My first board was a Fanatic 5.8x110l with the boxxes way too far to the back (didn't know that then), and had the same problem like you when changing from low aspect foils like the GF Maliko and IWA to more modern foils. So after some searching I came out with the AK.
I used to like a lot of frontfoot pressure and even The W1000 still has space in the front left, while a foil like the Kujira1210 (lot of forward lift) can go far enough to he back. Noawadays i,m more evenly balanced and never need the outer range of the box. Besides that, the board is light, very quick up to plane and feels smaller as it size suggest. I have it for 1.5y/aprox 200 sessions and no soft spots etc etc. All it needed was just 1 small repair on the bottom because I probably did hit something.
The difference between the 5.8 of last year and the 5.6 are very little, so If you can find a last year model cheap its a steal.
(In europe an German onlines hop Keppler sells them for 760,- exc shipping).
