hi Matt
In the Wabitech range of spear guns I have used a 1.2m carbon, 1.3 alluminium and 1.4m alluminium. They are very nice guns and as most who have used them will tell you that they have a comfortable handle better than the Ra's. The only other difference is that they have the plastic rail which is supposed to make less noise when firing and scare less fish.
I personally use a 1.1, 1.5m Rob allen and to be honest the rail thing about noise is hardly noticable to me, accuracy and range is exactly the same depends what spears and thickness mono you get. Get the one with the best price.
As for size on the 1.2 and 1.3 we had single 20mm rubbers, and on the 1.4 twin 16mms all were rigged with 7mm spears. Accuracy was spot on maybe the 1.4 was a little less accurate but then its a more longer powerful gun. For the fish that you mentioned Grouper snapper etc the 1.2 carbon would be perfect sorry havent used 1.2 alloy but would probably be similar. The 1.2 was used to shoot Coral trout etc Reef species over here. I also plugged the odd 30lb spanish mackeral which the gun could take easily even from a good range relatively speaking, not sure what bluewater fish you have there.
I swap guns all the time out there between my 1.1ra to dads 1.3stealth to my 1.5Ra. Any of these guns will get you the fish. I have shot my biggest fish with my 1.1 and a single band ?
For me I have owned Rob allen from the start so dont really see the need to change to stealth as they are so the same.
The guns that Jim mentioned are either what we call the edge railgun or the Torrelli railgun. They are made by Tony heughs down south and come in Alloy and carbon I think the only difference between these and normal railguns is that when you tilt these guns on the side the spear doesnt fall out of the track like ra and stealth.
Any of these guns will do the job just choose between a 1.2 or 1.3. And if your after some cool range get a 1.4 -1.5 yes Iya im talking Railgun range not Riffe range
cheers
