piston for the 310

[fastR of puppets]

im getting a esr prox 310 it comes with a prox piston, but im thinkin about asking for them to not include it, and then get a weisco, do you think it would make a difference or should i just stick with the pro x

hello,i have a esr 330 kit(76mm) let me say go with the prox.The weisco has a weak skirting they will break. this is a very common thing that weisco pistons do when you go wiyh a 310 or bigger. before you buy that let me know i am thing of selling mine.send me a pm if you would like to talk.
