No Promise but I can try the Riffe #2 with 9/32 (7mm) shaft. In fact I been using it more often than with 5/16" (8mm ), I think more accuracy, rough guess shooting at pier wooden pilings.
Never done plywood target yet.
I don't use 5/8 bands with my #2, don't have any. It is not that I do not want to help you but 3 of 5/8 bands can get me a bottle of Chivas or Jack Daniel at some club....so.....you know....he he he he.
My 9/32" uses only two wraps of shoting line, so about only +-4.5 meters. 400 mono too. If I use 2 bands of 9/16 ( 14mm ), the recoil is so decent .....sweet but the shaft doesn't pull the gun. If I use 3 x 9/16 rubbers, the shaft shoots lightning fast and wants to rob my gun from my hand at the end of its travel. Decent recoil, If I may say so. Accuracy still fantastic, I mean I shoot 5" long and 1.5" diameter squid and small rainbow runners....it tell the story.
I never even tried 4 x 9/16 rubbers on 9/32 shaft unless I lengthen the shooting line to 6 meters or 3 wraps. Next time friend.
The 5/16 (8mm) Hawaiian shaft with 4 x 9/16 rubbers with 400 lbs mono and 6 meters/3 wraps shooting line, still have left over energy to pull the gun away from me.
My other set-up of 5/16 shaft with Ice Pick and 6 meters/3 wraps of 500 lbs coated cable shooting line, this does NOT have left over energy at the end of its travel to pull my gun away from me.
If I freedive, I use my 9/32" shaft. If I do my usual wrecks I use my 9/16" shaft + Ice Pick with the cable. I have got so many 7+ kg Trevally with Riffe Ice Pick that are usualy lost when using JBL detachable Tri Cut, even on gill shots. I love the Ice Pick so much. It is a forgiving spearhead that rarely let fishes go even for bad shot and does not damage much flesh. Not reccomended for 7mm shaft though, too heavy and a drag during flight.
U know I scuba and do not use float. Trevaly has a habit of tangling the shooting line to the wreck, once tangled, it pull with all its might. By then it will be how good the spearhead will hold without tearing the flesh. There is nothing I can do to play braking effect. If I ascend fast after each shot to clear the line from the wreck, I risk decompression sickness and will be blasted away by the strong current. The only time I can get away immediately from the wreck after a shot is when I am done shooting and want to surface.
One or two of my wrecks are trevaly guaranteed if u do 3 scuba dives a day. I mean at least u get to pull ur trigger twice on those three dives. Sucks to many but to me, this is good enough. In coral reef area, a big trevaly has less chance to tangle than on wrecks but to see them there.................. not in my close by waters.....NO WAY !!!! Once in 10 dive is already lucky.
85% of my fish are either from wrecks, FAD and oil rigs.
This shows that equipment preference differ from region to region. Ice Pick is considered by many as a blue/open water spearhead but not to me. With my lack of fish, I managed to boost my catch many times over with Ice Pick and a Riffe. There is only one place I been in South China Sea, on an oil rig where the trevalies are so dumb and plentiful, they come to you. Here, any guns with cable shooting line will get u plenty of fishes. Don't talk about the 1 meter Barracudas, even Hawaiian Sling will get them.
Here is the typical trevaly we get in a 2 day trip of five divers with 4 dives each on our wrecks. Poor me already happy with these low productivity. On the other hand, I am still luckier than you Murat. Sorry.
IYA
