For close in work i prefer to float leger, basicaly put your float on held in place with your float stops, then a small leger weight 3/4 ounce sort of size, then a rubber buffer bead and then tie your hooklink on either hair rig or just standerd hook to nylon with swivel, set the depth and your away very resistant free with only having a float on the line,
If you go with the normal float set up, as long as you dont put the weights/shots on to tight they will be fine, if you need to get weights and you want a soft shot get Anchor weights and Dinsmore are abit tougher again personaly i prefer the Dinsmore shot as the Anchor ones can be abit to soft, if you are fishing near a weedbed and the fish has a chance of getting in there then you could put a small peice of silicone tubing on the line then put your weights on this, this will also allow you to slide the weights up and down the line so you can ajust the depth etc without having to open the shot up every time
