Shimano Calcutta - smooth, but expensive, plastic levelwinder breaks (met the guy who had it broken 3 times), sometime engages the gears during the cast (heard the grinding noise during the cast from other reels including the newest TE). Own a copy of Calcutta 700 (had gears misengagements)
Abu's - different models (from cheap versions for combos to more expensive rocket or magnetic cast control). Standard reels (6500 C3) can be modified to get better cast (extra bearings into levelwind) and smoother drag for big springs (as the standard ones can go only one-two seasons). Never had a misengagement problem. If you want a good reel - get the one with magnetic cast control and extra tension dial on the left side (like in 7000 models or Rockets). Own 3 abus: 6500 C3, 6500 CS (limited edition - magnetic control, 4 bearings, tension dial, extra long casts), BG7000HSN (resently). The BG is a good reel for Chinook (both bar and floss), but requires experience to for extra long casts.
My dream reel: BG7000HSN with super stopper roller bearing, extra two bearings in levelwinder, magnetic cast control.
Both reels should be regularly maintained, avoided contact with sand, and used only to fiight the fish not snags.
