feeling bites is always necessary, if your fishing for perch you can go down to a 8-10lb braid and 4-6lb flouro and you will feel it whan a perch farts near your bait there is a reason for any set up and using just trilene mono exclusively will catch you fish but don't we all want to catch MORE fish
Cudz thats exactly what I'm talking about I put enough for a rod lenth as a leader so I don't have to re tie the back to back uni all the time.
