1. Make sure when you put the line on it isn't twisting. How do you know? Reel some line on the reel spool and then put some slack in the line (push the rod and reel towards the spool of line), if it curls and twists turn the spool of line upside down and continue. Keep testing. If it gets put on twisty you start out very disadvantaged.

Very good point.  Different types of reels should be loaded with an eye for line twist.
Spincast reels should be loaded with the source spool flat, and there's a top & bottom.
Centre-pin type reels (bait casters, flyrod rigs) should be loaded with the source spool spinning.
