Tenryu upgraded the Rayz blanks this year, so the difference between the Rayz and the Spectra is not as wide as it was. At this point, I personally believe the difference between the UL, LL and L is more noticeable than between the Rayz and the Spectra. The LL (Spectra RZS51LL-BC) is right between the UL and the L of the Rayz rods. Even though the Spectra has the Torzite guide inserts, alignment dots, built in hook keeper and MUCH prettier wood, I would recommend choosing based on the weight of the lures you plan to fish. The Rayz UL is best for lures of 4.5 grams and under, the Rayz L for 4 grams and over and the LL for lures of 2 grams to 6 grams. I decided to keep the 4'10" ultralight Rayz RZ4102B-UL for myself rather than the "nicer" Spectra because I mostly fish smaller streams with lighter lures. If all your lures are right at 4 grams, so you could very reasonably fish any of the three rods, choose the one with the prettier wood
