The line would depend on if you plan to cast overhand (1-handed) or spey type (2-handed). It also depends on how deep you want to get. I happen to have the Scandi or Skagit heads with running lines attached for $50 eachplus $7 shipping. These lines were designed and built for the IF1086-4 by Steve Godshall from Speyworks in Medford Oregon. He also designs and builds lines for Bob Meiser and Gary Anderson of Anderson Custom Rods. They work Great! To discuss more details, give me a call at 916-962-0616 or email me at LLLee@L3rods.com. Thanks!
