When these rods were introduced last year, my initial impression of the 3wt was positive and the 4wt was rather negative.
A new delivery has arrived and I did a second test drive.
The 3106 is very nice with a Scandi 240gr, smooth casting with good distance.
The 4110 has evolved with a redesigned blank or unexplained improvements. It is great casting with a Scandi 270gr,,, a pleasant surprise from last year.
Both rods do not generate the line speed obtained from the new Sage Trout Spey rods however, distance is not the most important factor for smaller flies.
I did not test cast the rods with the new ultra short Skagit lines from RIO
Both of these Winston rods are lower in price than the comparable rods from Sage and Thomas & Thomas, a good value for a USA made product.
IMHO they are mislabeled as "Micro Spey" which to me indicates under 200gr Scandi lines and shorter than 10ft.
