Sean Dyer,
I have used quite alot of poles and i bought a few Ionics Swift poles, expensive but absolute quality mate, really are superb.
If you decide to go for 45 and above at any point get intouch with me and i know someone who makes superlight poles that are excellent.
I have used the superlight that i bought from him, at almost 90ft, quite awkward, but he is designing something to add to it to give it maximum strength without the bend., which will make it without doubt in my opinion the best out there.
Let me know and all the best
