Tracey Greene –
The X-Series spool is significantly lighter than previous models. It handles well on both freshwater and saltwater fishing. The XL frame fits my 8/9 weight line perfectly and feels balanced in the hand.
Nicola Black –
Great weight distribution and very responsive when casting. The XS size is ideal for smaller setups. I added dacron backing for saltwater use and it made a noticeable difference in line retention.
Keith Thomson –
Lighter than expected for its size. The XM frame works well with my 6/7 weight line. Easy to assemble and fits seamlessly with my existing reel setup.
