10lb. ball, 40-45 degree angle has worked me- unless I go deep the angle goes out further. Deepth finder speed, 2.2-2.8 for a hotspot - less for a dodger. I fished fresh for years. I now try and always brine. 3-4 big handfulls of rock salt to 3-4 gallons of water, then put cooler in refer over night. Make sure you get good quality frozen. If done right with good frozen bait, you can't even get the scales to come off in your dry hands.
