Jack,not sure how far a 1oz Dive Bomb would get u down but I would say add it on about half your stretch of line. I have been playing with Torpedo Divers a little this year and love em! Caught fish on them everytime I put one out. In some situations they are just awsome(like high fish)! They come 2,4,8,and 12oz and come with a depth chart.Check out the website,good luck.
