One point re Lead Core,allthough T Whatever sinks quickly and maybe faster than Lead Core you may find a lot of club,association,ticket and private waters still ban the use of Lead Core and as a consequence you could find yourself in a bit of bother using it in the wrong place etc. etc.
This is/was purely down to how Some People used it in past years-as an aid to foul hooking/ripping,generaly extracting Salar anywhere other than the mouth.As ever any very quick sinking stuff needs a little care and thought over its use,many Baliffs,beat owners et al still get a little nervous over Anglers using such gear,especially in low water with numbers of fish in the water.Not casting aspertions here merely pointing out a practical thought or two-I use such stuff myself from time to time.Pedro.
