What is Rio PowerFlex tippet?

PowerFlex is a copolymer tippet and leader material with a PTFE coating to help knots slide up tightly without pig-tailing from friction. It's quite a supple and slightly stretchy line and is popular for fishing dry flies, though works equally well for nymphing or fishing lures. The stretch can also help reduce the likelihood of snapping off if you get a smash-take, too.

Good stuff for dries, but equally good underwater too.

What colour is it?

Rio says this line is pale grey in colour but it looks pretty much clear to the naked eye. Their marketing says the grey colour "enhances its camouflage in the water", though I suspect it's not really a deliberate decision that it is this colour. We've caught plenty of fish using this line, so don't let the grey colour put you off.

We've caught dozens of fish on PowerFlex.

How well does it knot?

As claimed by Rio, PowerFlex does knot very well. Even without moistening knots slide down well and formed neatly without damaging the line. While we couldn't test strength without special equipment, we've not experienced any breakages at the knot yet, so knot strength seems decent enough.

Knots are neat and secure.

What's it like to use?

There's a surprising amount of stretch to this line. I reckon you could stretch a 1m section by a good 10cm before it wouldn't stretch anymore, so it's quite springy and good at cushioning lunges from fish, potentially reducing the risk of snapping off. The extra stretch doesn't seem to impact bite detection either.

We've found Rio PowerFlex a good copolymer tippet material. It knots really well, seems to have good knot strength and has proven reliable. It's pretty decent stuff. George managed to get several doubleheaders using this leader and didn't snap off!

George experienced several double hookups without snapping off.

How much is it?

When we bought ours online we assumed the spools were the usual 50m length, but they're actually only 30m, which makes the £4.99 price per spool fairly high for a copolymer material. It's roughly 16p per metre, so a typical leader of 5m/16' would cost you about 83p or around a pound if you add droppers, so isn't the cheapest but does seem decent quality for the price.
