I tie mine with 6 in drop on top, 18 in with 1/2. 20 with 3/4 and 22 with 1 oz. 1/2 for less than 12 ft, 3/4 for 10- 14 ft anything over go to 1 oz. that's all based on fairly calm conditions. Gets rough I will go to the 1 oz no mater depth. I do have a few double minnow rigs tied like bowmender for just minnows in shallow water. Just expirment and see what you like best.
