What is the big deal?
I don't get it, why do people feel the need to argue over gun disiplines in such a derogatory fashion. I feel like I am listening to a Nascar Ford vs Chevy argument. They are essentialy the same thing and becoming more simular every day.
O.K. I will make an analogy that I think covers the scope. Spearguns are like cars it really depends on the displine or application. I still think it is silly to drag race a front wheel drive car but it can be done and achieve results that are formidable. The guys that race them are masters of their displine. I personally think fwd belongs in a rally race. Then there are F1, SUV, Indy, TransAm, Mini Vans, NHRA, all will get you where you want to go it just depends upon where you want to be and how you want to get there.
I hunt with so many different guns and each one has its merits and disadvantages. I happen to be fortunate and have so much time to go spearfishing that I can hunt many different fish that require different techniques. When the conditions/environments vary I will change technique sometimes even with the same type of fish. I have had my best results whilst hunting with being very adaptable. There is always something to said for the dedicated who know every subltle nuance of their speciality, I just find it too rigid for me. There are three different ways that I load my euros. One gun I made was more of a study of theory than any thing else. Its mega length and huge elastics required me to make mini fold-out armatures on the stock that allowed me to climb it like a ladder using my leg strength to cock it. There are so many ways to skin a cat!
