Changed the Stroft to RIO Powerflex and what a difference
A five foot furled leader and another 5 foot or so of Rio tippet gave me the best presentation I've had for a good while.
Tried my Featherweight (also using Rio tippet) on the Zhu for the first time today and the combination felt good. So, I have my Condex with Cortland Sylk, and my Featherweight with Rio Gold both seemingly suited to the Zhu.
Oh, didn't take a fish but hey................
