He he he he..... I know u r going to say something of the premature EJECTION.............
The 3/8 x 36" ( 4" longer than it should be ) shaft on the MTO is very nice and accurate if 3 bands are used in either standard large head or my Apollo 11 confifuration. My friend loves to borrow the MT0 for small grouper and he bagged quite a few. If you use it for Halibut, I am sure you will love it. At 36" short the 3/8" shaft is so STIFF, you will never bend it....no way I think. I heard Halibuts are shaft killer. I just enjoy powering up the MT0 to incredible proportion for the fun. At 5 bands it is indeed difficult to shoot for bull's eye accuracy unless the fish wants to come close like Amberjack at 1.5 meters and big at 5kg upwards, just aim at the gills and it will be a goner.
I will replace the aluminum muzzle with the regular plastic one so that it will float, it is on order. All the sinking been ruining the beauty of the teak wing and the fine anodized finish. 4 bands will be easy to deal with anyway, no special aim required. However the gun is so sweet on my hand, the balance and quick aim is fantastic........

. Even at 3 bands, the 3/8" shaft (my 36" ) is at least 30% more powerful than with 5/16" x 32 shaft, the power increase due to the mass is just worth the conversion. It seems that the 5/16" shaft is still too light with 3 bands. Forget the 9/32" x 34" Hawaiian shaft, it is WAY too light and a waste of the gun's potential. So Uncle, you still wanna get the MT0 ??
