I have a Kombat 105 and it feels great.
My case was exactly the same as yours. A freerider making the transition to B&J. The kombat is a good choice. The difference I felt was that it is much alike a freeride board, with much easier - and higher - jumping abilities.
The only weakness of this board is the fin box. The US base was a bad choice from the designers, because you just can┤t find suitable fin sizes for sails up to 6.5.
