Kombat 122 tuf of skin, and mute of comments
there seems to be very little feedback on these boards. I was considering buying the 122 Kombat , but being a bigger guy myself at 90 kilos and needing something that would go good in 14 to 17 knots days i decided i needed something less freeride.
As to your question , considering the freeride design of the kombats , which is less freeride then a wave board but more freeride then a futura or the carves, i think ( and i may be wrong) they are not back foot driven boards at all.
so you may find marginal gains with big fins and trying to power of the back foot.
