Best bargain in 2-speeds. Excellent drags, light weight, low maintenance, lots of cranking power. Only limited in the really bigger game, over 200#, like billfish.
I like the TLD20II for 40-50# and the TLD30II for 50-60#. I don't have the TLD50II but have seen them work on triple digit tuna. An excellent reel for 60-80#; however, I wouldn't fish it with 100# and a 33# drag setting.
Spectra can be a good thing if you're prepared for the extra care and skill handling it. The reward is awesome capacity; no need for any backup outfit.
