I'm not as good as some of the guys on here and I can only suggest what I do and use.
Firstly convert the poundage of your test curve into ounces then add half an ounce, that'll give you your optimum casting weight.
Tighten your clutch right up
Have a good drop on your line, the lead around the spigot joint on your rod is a good point.
I use a braided shockleader
Most importantly use a finger stall, generally speaking, if you aren't putting your casting finger at risk, your not casting hard enough.
Try to get the cast as near to 45 degrees as possible.
If your right handed, left foot in front, right foot behind and transfer your weight from the back foot to the front whilst casting.
That's how I do it, I'm sure there will be other methods
Ooo last but not least, tournament leads and helicopter rigs. Make sure your rod rings are wet.
