Muskyman,
1) 25ft of 14lb-17lb sufix invisiline works well for me matched with a max of 30lb braid
2) colors, well they all have their days but like the fellas above said purples and greens work well consistently.
3) As far as your boards go they should track fine, but if your set on making an adjustment; for leadcore on the big lake I made a small adjustment by:
a) taking the rear screw out,
b) drilling a third hole the same distance in front of the front screw,
c) and then slide the weight forward and replace the rear screw in the new hole,
The adjustment allows the weight to be adjusted further forward putting more board in the water and creating alot more pull. This should do the trick for ya you'll have to play with them a bit once you get on the water to get them dialed in but it should'nt take much.
Good Luck,
Shawn Banks
