It's a liros magic pro sheet that comes with a spectra core. originally its only a 6mm rope but i removed the core and added another 4mm core inside the core. the extra core fattens up the sheet just nicely.

24x4mm = 96mm or 4 inches there abouts. but the splice has no structural value as the core runs the entire length of the sheet without joins and carries the load.

Pepin, your right about the taper, havnt finished this sheet yet, just happened to be making a new one tonight.
