Pacific classic and Klip Legend are not lower end guts btw. They are classic uncoated (or in teh case of legend crappy coated) guts like you used to find 15 years ago. Today are considered mid range guts The current wilson and Bab guts have a heavy coating which they charge you extra for.
In my opinion, the classic uncoated mid range guts play like what a gut is supposed to. The higher end coated guts feel weird fresh and play different as the coating wears through. At the end of their life they play like Pacific classic when the coating is gone.
