Small deetails- Eliminating mistakes

I have not fished the last couple years due to an all summer dock replacement and last year our daughter got married and we worked on the house they bought. Anyway I have been thinking what I have done wrong that I cannot catch more fish consistently in the past. This is what I have done this winter.


-Bought a Fish Hawk
- Bought Precision Trolling App (instead of using charts I downloaded)
-Added flags to my planer boards
-Bought 4 new Eagle Claw Starfire X rods for planer boards so my planer rods match
-Bought new Okuma Magna Pro reels for the planer rods.
-Will be using my two matching Diawa Accudepth Linecounter setups with the yellow braid for dipseys
-Will use my two Cabelas outfits with green Power Pro for Tru Trips
-Bought P line CXX mono instead of the Bass Pro mono for the planer reels.
-Calibrated my reels
-Bought a new Garmin unit for fish-GPS
-Bought two Planer board bags to keep boards protected and organized.
-Bought a Lakewood mesh bag to keep my clear tackle bins in one place.
-Bought crankbait locks to attach from my line to the hardbaits.
-Fish stickbaits about 3 ft above the fish and avoid the pack of boats.

My questions today are this.
1. Should I paint my orange Dipsy divers black?
2. Between my Dipsies and my bait, can I use the P-Line CXX or do I need flourocarbon?
3. I bought Pro Cure scent. Use that all the time, or when the Bite is slow?
Thanks
