If you search this forum you will find hundreds of post on various topics that cover the "best" rod for sensitivity, the best line, mono v.s braid v.s flouro and not to mention "which brand is better" wars. Well, IMO, having the "best" equipment or the most recent produced reel or lure isn't going to make you a good fisherman.
Several of us on this site fish at night as well as day. To me, fishing at night is a whole new ball game. Not that your technique changes a whole lot but because of visibility. I rely on feel more than line watching, even in the day. And yes, learning to feel the strike can be accomplished without having the most sensitive rod.
Here is what I do to hone my skills besides putting in hours and hours of time on the water.
I practice fishing with my eyes shut. It doesn't matter if I'm using a crankbait or worm. I close my eyes after my cast. I keep my eyes shut and rely solely on feel to detect the bite. I use my finger against the line to help detect the strike. I then use the tip of my rod and my finger against the line to tell me which direction the fish is traveling.
I'll also take my practice a step further and block out my hearing. Use ear muffs or plugs but be prepared, this is a bit freakish. Closing your eyes and ears at the same time can be kind of scary. IMO, by not utilizing 2 of your senses forces you to rely on feel and instinct which, in return, will make you a BETTER fisherman..
Another technique is to try casting with you eyes close. Have you ever tried watching your worm sail through the air at night? Can't see it can ya? I use a 3/16 ounce weight most of the time when I worm fish. Get used to knowing how long it takes your worm to travel a certain distance with same amount of effort put into each cast. I pick out a target on the water and then close my eyes. I make my cast and see how close I came to hitting my target. This technique really helps me at night when it's hard to see where I'm casting.
I hope my practice techniques help when it comes to honing your skills.
