"Wrigglers"

[devonutopia]

What I (and my Dad) have affectionately called the small eddystone eels that "wriggle" as you lure them in... Now I have general found tinsel traces to be better lures, but when would eddystone eels be perhaps the better choice of lure? Maybe times when vibrations/movement is more evident than sight, such as in cloudy seas / cloudy skies? Often wondered as I have the choice of using either when going for a spot of spinning and often just fall back on the tinsel stuff.
