I agree with your assessment of LLBean, and that they are competing against other "big box" retailers. My wife & I go to Maine every couple of years to fish the Kennebec River for trout. And we stop in at Freeport to shop for clothing & home stuff at LLB's. But we buy our fly flinging gear from dedicated shops such as LRO and others, because their selection is better and more inclusive of items that we need. Plus they are good sources for up-to-date information on the streams & rivers and what is working.
And we would rather support the "local" stores & shops. The last couple of years have been very difficult for fly shops, and as Byron has lamented on his "Fishing Report", a number of fly shops have been forced to close. Don't want to see that happen!
