I'm really digging the Tama cobra coils since I like the pedals really tight and responsive. Problem is I can't find anyone who sells the coils in the US. I have some new Iron Cobras and I just cant crank the spring down tight enough for my tastes. My two go-to online stores (musiciansfriend.com and music123.com) are coming up empty as are pretty much every other store that sells online music stuff.
