The best way to get better at fishing tournaments is to fish with guys who are better/ more experienced then you. A local club might not be the best route. Back in the day - I had a year of fishing Red Man tournaments as a co-angler under my belt (Redman was the precursor to FLW & BFL) . Anyway, I decided/got talked into joining a local club that was trying to start up. There were 30 or so members - more boaters than non-boaters and decided that they were going to fish a semi-regional tournament schedule. By the end of the year I had discovered that all any of the boaters knew how to fish was to beat the banks. The problem was that I already knew how to beat the banks.
When I did the math on out of town tournament expenses, I found out that aside from the entry fee, expenses were the same as BFL, i.e. I stayed in similar motels. I didn't eat any different. My gasoline expenses were roughly similar - everything was similar except for the entry fee. the BFL co-angler entry fee was higher than the club entry fee.
After a year of club fishing, I did the math and decided that I didn't learn enough fishing in the local club to justify the savings. Going to the BFL's and drawing partners whose fishing skills went beyond the banks enabled me to learn a lot. Hanging out in the parking lot the couple of days prior to the tournament, I learned a lot of stuff that I could apply to my week to week private fishing and also to the tournament situation.
I'm not saying don't join a local club. I'm just saying that in my opinion, fishing in a local club set back my skills accumulation compared to what I learned in a season of BFL. AND the BFL didn't cost that much more
A national or regional tournament organization might be a good choice for you also.
