Well boys..... I have all the points to solve the premature ejection.
I have both mother(s) in law u boys mentioned..., in fact I can say 3 if a engagement-went-bad future mother in law can be counted .........how's that.....

plus my Amex bill for all the Riffes.............
Ur set up for the MT0 sounds good Sven. If the Halibut lies on the sand as I seen on video and u shoot from the top, you will have plenty of dinner.
+karma if u get that MT0 for free.......... was it from ur ex mother in law ?? Wha ha ha ha.
Hope ur ankle recover soon. I recalled the day I kicked a cabinet and sprained my feet and I was diving with one leg....

, no current zone, so its quite OK.
BTW, do you need to shoot halibut at an angle ? With possible hard sand or some rock under it, won't the spear penetration get hampered ? If I shoot a grouper which has a rock on its side, I can't shoot at "T" angle, the spear will bounce, I need an angle.
