Richie, try Matt's DIY WFP forum (google for it, links aren't allowed here); those guys have used just about every conceivable type of pole as a WFP and it's pointless reinventing the wheel.
I use both the Harris and DIY fishing poles (you'd be to get upto those high jobs you're after with one of those at maybe a fraction of the cost with the fishing poles; have a look at Jeff Brimbles posts.)
Regards,
Tosh
