hey jack(o)b
i`ve tested an igo (for about a half an hour) and i have bought myself a rad180.
igo:

its avery forgiving boat and super easy to spin and (flatwater)wheel.
but the bluntig is bad . i just coudn`t get my ass off the wave.
(bremgarten lower)
dindn`t try loops or all the other stuff.
a lot less valume ,i thougt.
i prefer more volume.
rad180:

i love this boat. lots of volume and super-short.
flatwater wheels take a little effort but i`m still learning to deal with the volume.
(had a king-pin6.1 before)
loops like hell ! good hole boat because of volume reserves.
and gets you flying
(actually designed as a wave boat)
great outfitting (for those who care) i just turned the backband so its upside-down
Didn`t find any bad things about it yet.
i would take the RAD
cheers theo
