Zip jigs with mylar - certainly have the flash - add a mini curley tail and they move
from spider rigging to long-lining. With the curley approach have found that spec's
are much more orientated to color vs wiggle.
Speed also brings into play a lot of variables, wgt of jig and distance to depth move
moves attractant up/down water column.
Sometimes the lighter the jig head whether single or double is controlled depth wise
by amount of split shot added to main line as well as space between shot & jig.
