The Big Games had some issues, unfortunately the drag was not user serviceable and also not completely sealed. consequently water (freeze up) or salt and sand could get into the drag and render it worthless. Both of my Big Games had a few failures.
I agree completely about drags with you Burke. They should either be easily serviceable by the owner, or "completely sealed" (forever) by the factory. I too have a partly sealed BG5 which I completely submerge after every use in hot water and dawn dish soap to remove the salt, otherwize the drag does not function properly the following day.
The Canyon BG series have both ported spools and a ported frame - exposing the drag to salt water - unlike the Tibors and Pates (and some others) which do not have either ported spools or ported frames on the drag side. Additionally, the drags on both are easily serviceable, though they rarely need it.
I also had the handle freeze up on the BG5 so it doesn't spin on the stud. This, I believe was due to too tight a tolerence between the plastic handle and the spool.
Much to their credit, Ross Service sent me replacement handle, stud and machine screw at no cost at all and the same day I called, so I wasn't without the reel in the interim.
I machined another 0.004" off the face of the new plastic handle to give a little more clearance and have not had that problem since. I understand their thinking in the tight tolerance since the tighter the fit, the less deflection on the small (necessary) machine screw and thin aluminum of the spool surrounding the screw head. But I don't think the additional clearance is going to cause a fracture from "work hardening" in this instance.
Incidentally, when replacing small screws in reels, I have been coating their threads with fingernail polish since I was 12. It makes a big difference in cutting down - practically eliminating- electrolytic corrosion. It breaks free easily when using the proper sized screw driver.
