Great responses......I am going to try them I will try to post my
feedback....it has been a wet year in Oklahoma and my cables are in need of
changing...I am a sucker for the latest and greatest.....even if the latest
is not the greatest....LOL I get caught off guard all the
time....(Ergobrain, Tufo tires, ext...) of course these products might be
good still they just did not fit my purpose....
we shall see.....thanks for leaving all the great feedback...
