I would like to know if anyone has ever strung up with Nickel on a few strings and Steels on the others? If so were there any tention problems? Or other good/ bad experiences. 2nd question (and reason for the first is. I had Stainless on my 5 string, loved it on the B and E and sometimes the A, but it was to bright on the D an G. So I put on some Peavey Nickels (Cirius) Now I love the D and G but the B and E are completely life less. Could even be bad strings. Has any one had a problem with these Cirius strings before?
