Abigail Oliver –
Great value for the price. The 30# dacron worked perfectly with my 9wt rod for catching stripers. Easy to load and holds up well during casting. No breakage even in strong winds.
Connor Vaughan –
Used the 20# black dacron for bass fishing. It’s durable and doesn’t fray. Works well with my 6wt rod. A bit more expensive per yard than expected, but worth it for freshwater use.
Amelia Young –
Ordered the 65# GSP for tarpon fishing. It’s strong and reliable. The color matches my spool well. No issues during long sessions in the bay.
Ian Morrison –
The backing is easy to cut and install. I used it with my 8wt rod for bonefish. It performed well in saltwater conditions and didn’t stretch under pressure.
Nicola Wright –
Perfect for my freshwater trout setup. The 20# blue dacron is smooth and doesn’t tangle. I’ve used it for several weeks with no issues.
