as others have stated, it is all important but i think lake breakdown is the right spot to start for sure. I don't always get on the water practice or go into new lakes relatively blind. I think understanding how to break down a lake using maps, charts, etc. is super important. I can always make time to get on Google Earth and chart viewers ahead of tournaments.... sometimes this leads to reasonable success (catching fish), sometimes it doesn't (skunkfest). It is really about having the right mindset when you launch on tournament day. If you've broken the lake down, with or without practice, and are comfortable about where you're launching and have a plan of spots you want to hit, it makes a huge difference in how enjoyable your time on the water is when money is on the line. I think from lake breakdown to me it probably goes to adjusting to changing conditions. When to leave a bit to find a better bite, when to put down something that is producing a small bite to find a bigger bite, etc. All of these topics are equally important so looking forward to your take on each.
