Wondering if anyone has the 7wt redington prospector switch and what grain weight Skagit line they use. The rod recommends 475 +- 50 grains but Rio's line recommendation pdf for this rod say 375 for option A and 425 for option B. To me it seems like both those are really low on the grain window. I'm a grad student and money is very tight so I'd like to get the best grain weight first without having to buy alot and test. Thanks in advance.
