in the store u wont notice the difference besides graphic and that the spark is cap construction...but ive tested both and they are very different skis
the ignition has extremely soft tips and tails...i would almost compare it with fungitives or invaders except that they are not cheap. the ignition is a very specific ski with one thing it was really built for...pipe the tips and tails are 2 soft for jumping and they chatter like mother fuckers at speed
but they exceled at bumps and buttering
the spark i found was a much more solid ski, not only does it look more appealing but it overly skied better...it was amazing on jumps held up great at speeds and still buttered very reasinably for having stiffer tips and tails
over all unless u ski lots and lots of pipe/moguls id go for the cheaper and better performing spark
