The only down side to an egg sinker on spectra is that quite often the egg sinker will start to fray the spectra, whereas the plastic sleeve on the halibut slider will not cause the spectra to fray. I'm not saying this always happens but I've seen guys lose fish due to the spectra fraying, and like the old saying goes "your only as strong as your weakest link" in this case knot.
* and no Jim I don't want to have a debate about this hahaha
