I totally agree with the above.
Just got some Mizuno Wave Harriers (the ones advertised in the FRA race book) and its early days but I'm impressed so far. They have a very stable, non-twistable sole thats good news for over pronators. By comparison the Swoop felt unstable, more likely to result in a twisted ankle for fiolk who need lateral stability. Good cushioning, decent grip, but not nearly as grippy as Mudclaw's. Also the Mizuno is wider than say a swoop, so fewer black toe nails for folk with wider feet.
I think the Mizuno Wave will be very good for long distance stuff and harder surfaces (e.g. 3P last year where Mudclaws were too minimal for me), and for training, while Mudclaw is a better shoe for shorter distance races and really wet and muddy stuff as I guess the fabric on Mizuno will act as a bit of a sponge.
Biriani for endurance, pathia for speed.
mizuno waves are good in light muddy areas , as i managed to not get too far in a deep bit of mud but joe managed a full knock over whilst out on a gen jog..
Does Swoop wear Swoops?
Does it have your name on it??!!

There are some Reebok Inca Cross country spikes on ebay they have studded heels -depends on your shoe though
