Replying to Scott P4's vs. Gotama's

After all this snow in the east, i really wanna grab a new pair of big boys. I ride the karma's and love them. being a fan of volkl i was looking towards the gotama's. then i was reminded of the p4's. I hear both skis are realatively stiff and pretty decent for charging but would also float real nice in pow. i'm a smaller guy at 5'9'' 135, but i do like to ski hard. anybody know how these skis compare? also does anyone know how they compare to prophet 100's?
