The original design goals for the Vector were as follows: • Ease of casting (< 4:1 ratio line to rod length); • Balanced flight characteristics (shootability); • Strong roll-out and stretch (straight layout); • Excellent fishability (not too short or long, and integrated holding/running line). The Vector series embodies all of those goals. BALLISTIC “VECTOR” SPEY LINES_Specifications: 4/5 Weight Head 41' 350 gr. Running 60' Total 105' 5/6 Weight Head 45' 390 gr.
