The Solitude series reels come precision machined from aerospace-grade bar-stock aluminum, fit with stainless-steel parts and components, and equipped with a fade-free, cork/Teflon sandwich drag. Computer-controlled lathes machine both the frame and spool to 0.0005-inch tolerances. All other integral components are manufactured from 100-percent stainless steel. The rounded outer surface (a concept inspired by the basic design of protective armor on tanks and ships) has fewer edges and angles to ding or nick, and deflects blows from dropping to prevent exposing any raw aluminum to corrosion. And the computer-designed spherical frame delivers one of the highest strength-to-weight ratios in the industry.
