[spaghetti]

Hi there.
Yes I am the Spaghetti that Mr.X was mentioning. Just like any Mediterranean spearo I always carry 2 or 3 guns of different length and set up, to match the different hunting situations having always an appropriate gun at hand.
However, if you're not willing to spend money for a second gun by now, tha shouldn't be a big problem.
In facts your gun, with a 120cm shaft, is likely to be in the 75/90 range, which is a good universal/overall gun for hunting in reef.
You will learn that you can shoot into holes and crevices with your gun (better if loaded at first notch, not full power, to avoid trashing your shaft): all you need is to do some practice and to find an appropriate technique. Train yourself to peep into holes upside down (head doqwn, fins up), to pull the trigger with your thumb (this will give a bit more of arm stretch when shooting), to shoot with your head near the hole and the gun strethced bacwards. If it's a 75cm bandgun, or an 80, I really can't see no problem to use it for shooting into holes.
