Lamson Force SL Series II -5+ Flash. SPOOL ONLY. 4.10" diameter, 1.0" width, 3.31oz and capacity WF6/125 #20. For weights 4, 5 & 6. Even lighter than the original, the Force SL Series II breaks its own record as the lightest machined reel on the market. This evolution in the Force Superlight reel lineage includes an even larger arbor to increase line retrieval and decrease weight. Plus it has an enhanced CNC machined structural development and more fluid, refined styling. Since coming onto the scene in 1997, the Force reels have pursued what we feel is the Holy Grail of fly reel performance: delivering the highest possible ratio of retrieve rate to reel weight. To this end, while other super arbor reels add weight in order to gain speed, Force reels maintain their featherweight specification by being pure muscle and bone. Large Arbor, 6061 Aluminum and Stainless Steel, Sealed Conical Drag System, Made in the USA!
