Using a reel that holds 150 to 250 yards of 20# braid and comparing it to a reel that holds 100 yards of 6# braid is senseless as the OP is not talking about this size reel for Cuda!! Kinda like what is the difference if you chase Cuda with a reel that uses 150 or more yards of 20# test Braid, or chasing Bass and large Walleye with a reel and rod that weighs less than your reel alone, and holds less than 120 yards of 6# braid!!
As far as holding up to saltwater and fish that put Jacks and Cuda's to shame. I would ask myself "who can pretty much buy anything" he wants, I would ask myself why Jose Wejebe was so successful and why he used only Shimano's, and I assure you he could have afforded anything he wanted to fish with, and was one of the top Saltwater Fisherman in the world, along with many many other Pro's!! Larry Dahlberg for example, also no chump!!
Yes Exactly! you just said it was available, for some reason you didn't make it clear enough what you wanted, or maybe the way you came across to the rep is why you didn't get your order, but as you yourself said, It is an available part, how dare them have it on back order????? But that does mean YES IT IS STILL AVAILABLE and will be in the future!!
Shimano should have never had a reel selling so fast when it was introduced, that way they could have had the shelves fully stocked with spare parts before you ordered it, but it was a hot seller and one of many models they couldn't build quick enough at the time. Like you said in so many round about words, YES the part was is and will be available!! But sometimes we have to understand, when they are making the most demanded products out there, it takes time once in a while to keep everything available without stopping production of other parts and products!! When you are Using the most demanded reels available a new model, with the highest demand at the time, you may have a time now or then where you have to be patient for a particular item?? I am not saying this last senario about you, but it does happen, a lot to do with getting your part quickly comes with how you speak to the reps, when you order it. May be why some always have trouble and some never do??????? Just sayin!
