It's interesting to hear about the Hammerhead guns starting to take off. Do you mail order them direct from Hammerhead or are stores carrying them? What are the prices like? Anybody using them already. Anybody able to compare them to the SA railguns (Rob Allen, Rabitech, Orcas, Pelaj)? Pity they have to ship from Hawaii, that must be about as far as Europe from the mid-West - no US import tariff though.
I have a 90cm RA aluminium railgun with 6.6mm spear - probably quite similar. It's a very strong & versatile gun. Although, having recently been introduced to the joys of the super light Omer XXV, I will look more seriously at the carbon barrel models in future. I hear they are not currently importing the XXV into the US -- probably worried that folk would try to overpower the slim 25mm barrel. We're love 'em in the UK, they seem particularly well suited to our small fish. Already thinking of getting another one, 90cm. I would think the Cayman & HF/HF2 Omers would be interesting alternatives. Actually any of the models featured on Hammerhead's target comparison chart (RA, Picassos, Beuchats, Dessault, etc., etc.) would be worth considering. I personally would not place much value on their accuracy comparisons - if you do, you might also want to consider the Seatec Gabianno, which has a reputation for great accuracy (in Italian target competition according to Spaghetti) and robust construction.
Wongs & Riffes of course, for the minted.
