A lot of factors dictate wt needed on NJ beaches,wind and current/tide flow being the most important.Generally for summer I only need 5 oz.If you plan to fish in the spring or fall,you will need more wt[up to 8 oz] and an appropriate rod.I use 9',10',11' & 12' rods.9+10 for up to 6 oz, 11 & 12 for up to 8nbait.Hope this helps.
