Yep, I've found Mark very helpful and his shop had everything I needed in one place.
Out of interest what do you think of the blank?
My review is on his ETSY site.
I was out on Sunday and as the fish were not playing, I had a muck about with leader lengths, casts, flies etc to try and find a weakness in the rod.
Super sweet delivery of dries on 9-12 foot leaders, even in an iffy wind. Handled shorter casts with a duo rig, although when I went above about a 2.5mm tungsten bead and a few wraps of lead it started to struggle a little with the GT90 line. A switch to the SLX and it picked up and delivered heavier flies nicely.
It threw small woolly buggers nicely as well (slx), although I am tempted to go for the 6 weight blank for that...still not decided yet.
I really do think I will be leaving the £500+ carbons at home and will be fishing this rod an awful lot this year.
I also have one of Marks 10 foot 2 weight nano-helix rods I built. Oooosh! That's a stunner too!!! Superb grayling/French Nymph rod!
