i couldnt really say to be honest, because i dont know! i would be just as happy using tubing, but i used leadcore years ago, before i started using tubing. leadcore was origianally a flyline, i had loads of the stuff, so i used it. it was no where near as good as what is for sale now. if i had started using tubing more when i started carping, then chances are i would still be on it. either material does the job well, but tubing is more user friendly. ive got esp rig tube in my tacklebox as well. and still use it from time to time.
