Dual trim from gardiners is what I use, used a vikan to start out, and even with my ridiculously heavy brodex fibre glass pole, it made a difference to weight, and is great for scrubbing.
As soon as I can, I will be weighing in for an slx, my back and shoulders are killing!
I was warned about buying a carbon pole as 1st pole as I would be at risk of damaging it, until I get used to having a 25 ft pole in my hands! I bash ity off all sorts!
