Wow, so many topics in one thread. To answer the original question; no, stores should not try to tell people what to buy. If a person has questions about what is productive, or legal, then yes a store should try its best to create an informed customer. But if someone walks in and knows what they want they should be able to buy it. Plus, if a guy really wants to bottom bounce there are several ways to create your own weights. Many of which people would lose their tops over if they were banned.
As for the issue of flossing and the regulations, I do not think the DFO should dictate how sport fishers should fish when they allow other user groups that have a much larger impact to have free reign. Why not say fish wheels only, or fish traps only. They are effective and allow easy release of non target species. Sport fishers cannot have an impact on stocks in systems as large as the Fraser. Blaming them, and controlling them is nothing but a publicity stunt.
As for the issue of Flossers and other fisherman. To me it is a simple, why does a person fish. Does a person fish to put meat on the table or does a person fish for entertainment. I fish for entertainment. I love going to the river, setting up my bar rig, having a wobbly pop and hanging with friends, casting spinners to schools of pinks trying to see how many I can hook, watching a Coho jump and throw the hook. Smile every time. Then there are the guys who fish to put meat on the table. They want to know where there food came from, and know they had a hand it putting it there. A very effective way of doing this is on flossing. If they take there limit and leave I have no problem with it. They bought their license, bought their gear, put their time in and have as much right to those fish as I do.
