Nick, If you want small but strong and are willing to spend a little then check out Johnson Worldwide's Spiderwire, Berkely Gorila braid, Stren Powerbraid (Dupont). And (a cheaper but hard to find alternative)-Powerline Plus(I'm not sure I got all the names right-esp the last one) These are all Spectra or Kevlar braids. They are available in very high breaking strengths. The average inland tackle shop/sporting goods dept. tends to only stock strengths up to 30-40lbs but they are available much higher. The 50lb breaking strength is only about .010 inch diameter. You can find the higher weights in coastal areas(should be easy for you now) or can order from a Marine Tackle supplier.
