What they said !
Line diameter and quality + a properly filled reel all help .As will learning the basics.
Slow start and a fast finish loads most rods more effectively then trying to go flat out from the start.
Look up! pic a spot in the sky @40 degrees and aim at that when your going for distance looking at the horizon tends to make the cast go low.
Experiment with the amount of drop ( the amount from the tip to the sinker) longer means a slower and softer feeling cast while a short drop makes your timing more critical and the rod feels stiffer.
Find what works best for you and your rod . Some rods work well when using a 4 oz lead and bait where some dont start to bend until you have 6 oz +bait on them
