The is another braided line on the market. The brand is Calcutta. I believe it is a spectra base rather than kevlar. It seems to be rounder and smoother than PP. We've been loading it on reels since last spring and haven't heard of any problems. It might be a little larger in diameter than PP but it lays nicely on the reels.

With any of the braided lines, make sure you lay down a base of dacron or mono. If you don't, the pressure of fighting a fish can tighten the braid and it will start to spin on the spool. That is not good. In addtion to stopping the slippage, it cuts down on the amount of braid you need to fill the spool.

You can find Calcutta at Swains Outdoors in Sequim.
