i casted one of these spey lines on my 13 ft 6 lami in 8/9/10 and 9/10/11 on my 14 ft 6 at kaufman spey days with george cook. it seemed to cast very well on these rods. can you use these lines with polyleaders instead of buying a versi tip. i have 2 kids to take care of so cant afford to spend 250.00 on two spey lines. any recommendations would be greatly appreciated as i am a rookie to spey rods even though ive casted these rods more than a few times and i am getting better every time out.
