Lancer and Cobb series have the same blank material as the more expensive series. Guides are generic aluminum oxide but seem to be good quality, and the seat, again generic but good quality is very similar to the fuji used by many companies. Absolutely better blanks than the Curado, guides and seats are probably a wash. $29 gets you an upgraded reel seat and Fuji K frame guides with the Tharp series. $50 gets you an unsanded blank, upgraded seat and zirconium guides with the Invoker. I bought the Lancer because my Pro SP palms better with it in my hand vs the Tharp Money Maker, and I bought the Cobb "One More" because that blank isn't available in the Tharp or Invoker series. I think the Tharps are the best value of the bunch, provided they have the blank you want in that series, but they're all very good for the $$$.
