your rope looks way to stretchy to wakeboard with ecspecially if your usin that with a tower too. It kinda reminds me more of a waterski line. Get a line like pro combo from liquid force and trust me it will make your riding 100% better and easier.
That same company has auctions for Spectra core ropes as well. Some people on the board have gotten them and like those. You might try one of those. They're going for about $50 on average.
Mike if you get the other kind of specta like Wayne mentioned let me know how it is because I plan on getting one but I want to know how good it is first.
A good rope may be expensive initially, but it will last a really long time; assuming you don't run it over. I've had really good luck with the yellow jacket.
the yellow jacket lines are real nice and very durable - long lasting.
The spectra lines are lighter and work just as well. They knot rather easily and they wear out faster then a yellow jacket style line.
Your rope in the picture above does not look like spectra, but will probably work just fine once it is streched out properly. Tie one end to a tree and the other end to your truck/car. Slowly and easily strech the rope using the vehicle. Carful - don't damage/break your rope.
Just go to your local wakeboard shop and get one, they SHOULD know what they're doing...not meaning they will...so, how long are all your ropes out there?
