Until last year I was using the Excaliber. Then a guy posted on a board about the teflon sleeve inserts in the excaliber causing line twist and heat on the fishing line itself, and said they were no good because of that, but that Tru Tungsten had no inserts and were polished smooth inside and did not cause that problem. So my roommate was setting here and says, "let's find out!" and goes on Cabela's and ordered some Tru Tungsten weights. To make a long story short, once we got them we both put them to the test out on the water. The outcome was; 1 we never had any of the above mentioned problems with Excalibers and their inserts, 2 we could never tell any difference between the Excalibers and the Tru Tungsten weights, 3 No discernible difference in the sensitivity transmitted to our hands by either the Excaliber and the Tru Tungsten, and lastly 4 I still use Excaliber tungsten worm weights to this very day. Anyway that is my experience with both, hope it's helpful to you in some way. Rob
