If you only had three rods

[Bad Habit]

I went with :
7' Medium 8-15lb with 3000 reel
7' Med Heavy 12-20lb with 4000 reel

What do you recommend for line sizes ?
I was thinking 15lb braid for the Medium with 20lb flouro leader, then 20lb braid on the second with 20lb leader ? Or do I just leave them both 15lb and call it a day.

You need 1 more- 6' med hvy 12-20 with a soft tip for accurate skip casting under docks- most average height people can't do it with anything longer than a 6' rod
