Here's a short history of events with my EP's:
1)Installed them-days and days of stretching.(about 10 days)
2)Settling down, very stiff under the hand(about 2 weeks)
3)Sound good, feel good (3 weeks)
4)Dead (about 9 weeks)
If you want gut, get gut. Metal, get original Flex or FC.
Similar story with Passiones (sp?) Marketing baby, pure and simple. Don't fix what ain't broke.
FWIW,
S.A.W.
