Trilene Big Game 1 pound spool

[StarsnStripers]

I have heard I will save money buying the 1 pound spool. So I'm gonna go with one, but tell me, which color, overall, is best??
Ultraclear, Green, or Solar collector??

Also, Am I going to need 2 different pound tests, for I will be using 15 for my Penn Spinfisher 5500SS and Daiwa Sealine X lure fishing combo, but will I need more pound test for my 7' Ugly Stik tiger with Shimano Baitrunner 6500B?? I will be throwing live and dead baits everywhere with the baitrunner, regagrdless of amount of rocks/underwater structure, should I make it a bit heavier??
