Well personally i would go for the profile, looks great, sound great (alot nicer than the chris king imo), and rides very smooth. The way i look at it is whats the point is spending £300 on a chris king when you can get the profile, there is no point it may say it has more engagment points but i have ridden both and they both feel exactly the same to me. But at the end of the day the choice is yours. Dan ! p.s - Stay away from front freewheel, never been a big fan of it, dont ask why because i am not sure just never liked it.
