TC Vs. Sparks big core again

[eastside 400]

TC or sparks big core for mx, basically low end, i know TC is great low end but is it worth the extra price, i know there loud so i dont need to hear about noise, just what is better, anyone have the sparks big core and ride with it?

[froggy97]

I have a TC and really like it, i got it just because it is so short and out of the way incase i get rear-ended or wreck

[culookn]

go with TC , i think it adds the most power all around

Sparks big-core along with hi-comp piston make good power everywhere.
