I've got a tournament coming up in a few weeks on a lake where I have caught some big ones in the past... problem is everyone knows about the spot and probably has caught their share of nice ones there as well.

My question is... do I grind it out among all the other boats fighting for position or should I abandon the spot and keep my head clear on new water? Opinions?

I let them fight for it, theres other big fish to be found. Then if they give up I will come back.

Define what aspects make this community hole so productive, then find other spots that share these attributes, and pre fish them to find out if they are worth your time.

Every lake I fish is one giant "community hole".  Pick a spot to get in the merry go round, and fish flawlessly.

If you can get some time, Id search for a few other areas that could provide the same quality fish, if you can't find any, I agree with ww2farmer, just get in the merry go round, and let the chips fall where they may!

it would depend on your boat number. if you are one of the first to take off. I would run to that spot try and pick up a couple good fish and maybe that kicker fish then once the crowd comes just hit your number two spot. if you are not in the first couple boats out your spot will probably be taken just find some other spots that others wont think of and give it a good shot. if you need to make milk runs to that spot multiple times throughout the day hopefully the fish will not be too spooked by all the traffic.
