As for sizes I like an 1/8th oz in the summer most of the time and a 1/16th oz on occasion.........a good heavy wire 1/16th oz head is a plus. In winter I use a 1/4 oz head almost exclusively...the heavier head tracks better in the heavier(usually)flows of winter. For the pink worms I do the same, 1/8th oz in the summer and 1/4 oz in the winter(the worm works much better in the winter than summer).
