Our top pick for overall knot strength, Stroft has found a place in our vests and sling packs here at the shop. By incorporating half sizes into their product line, Stroft offers anglers more versatility on the stream. Since it is one of the stiffest materials we tested, it is also one of the most accurate. While beginners may struggle to get a perfect drift with this material, for competition casting and the ultimate accuracy, we feel Stroft is second to none. The only downsides were their poor spool design and slightly higher average cost than other nylons.
