Hello again matey , again smuft has talked a lot of sense . I use running leads myself and imo is the ideal set up especially when you are starting out . There are some good threads about lead set ups on here with pics , have a gander .
Try and attach the lead to the line with a run ring as in the pics , and if you make the swivel a quick-change type it makes it easier to change hooklengths quickly. I tend to favor leads of 2.5 ozs or more .
Also , just in case because you didnt mention it , if you do use a pop up , make sure you have a split shot or a little piece of rig putty about an inch or 2 behind the hook otherwise your pop up will be 8 inches off the lakebed and look strange when your freebies around it will be on the deck , sticking out and maybe suspicious to a carp ?
A little pva stick or mesh bag on the hooklength will prevent the possibility of a tangle on the cast.
Again , have a read up on some of the stickies in the rig tying section .
Good luck and welcome to this wonderful forum.
