Love this board. I ride 5'3" and am 95Kg and use Pancho Large futures. Naish Slash 9m 14-18knots, 7m 19-25knots and then 5m from 25 knots.
IMO would not be ideal for straps as really lends itself to a dynamic foot position to make it plane like a boat, rather than setting a rail. It also prefers to be underpowered rather than overpowered. Mind you I have never ridden strapped beyond my first few months of kiting so I may be getting that wrong...
Excels in small to head high surf. The wide tail makes it get a bit sketchy once the surf gets to double overhead and above but you can still do it. I asked firewire if they could make me an Omni in kite construction for the bigger stuff but they said no

I personally slightly prefer it to the Vader and much prefer it to the Vanguard. Much looser but yet more stable in chop
