An extended form of the successful Sbirulino-fishing for trout and other fish is the use of crystal glass pins and weights. The pins are virtually invisible to the fish and can throw well and lead. For a little more natural bait presentation. In conjunction with semi-sinking or floating Sbirulinos the crystal chain between Sbirulino and leader is installed. Thus an optimal sinking behavior of the lure is guaranteed. The crystal chain itself is declining.
