the king

i got vent stripes but there too small, i think the proshop where i got the team helment and black vents are fake. i have a feeling this store got the dimensions and started printing there own to save money. i got them for free because the owner was nice so i dont care if i have to down $5 or whatever for some stickers. has anyone had this problem? do the cascade vent stripes run in different sizes? i checked some sites that said they had pro 7 vents and cpx/clh2/cpro vents... this is why i think the proshop has fake vent stripes. help!
