Will this fit my Cyrano 850 shaft?
I wish I could give you the straight answer. It seems like most of these spear tips come in two sizes. The larger size fits my spear shaft. You do want the larger shaft, because if you hit a large (18") Lion, it will bend your spear shaft like a pretzel if you are using the smaller diameter shaft. The six prong tip works very well. On Bonaire where we have eliminated a lot of the bigger fish, the six prong tip will snag a small Lion where the 3 prong might barely miss to the right or left and it will still get the large ones.
