I've just started using my Ninja pole, the pole Jeff Brimble produces. I got it a few months ago, didn't like it initially, and never really used it since.
But today I thought I'd spend some time with it, and you know what, I really REALLY like it. There's a bit of a knack to using it; it's a very light clampless pole; lighter than the SLX, and once I got the hang of it, it's so physically easy to use, it's almost a pleasure.
I think I paid £85 delivered (though I could be wrong), and I think it's worth a try if anyone is looking for a budget lightweight pole. I may even prefer it to my SLX (which is also a lovely pole).
