I would assume the Biller would do just fine. Most people that I have talked to from NJ seem to opt for a small euro (75-90 cm). Being how the water has cleared up in recent years, I just bought a 90 cm gun. It is a Beuchat Mundial, with 18mm bands and a 6.5mm shaft. It's a good gun, but given the choice, I would peobably have gone with a RA or Omer millenium. I only chose the Beuchat b/c I am living down in Grenada (south caribbean) right now, and it was the only gun I could get my hands on (you have to take what you can get here). Anyway, I am looking to trying it out when I get back to jersey this summer.
