Thats correct, it is the same pole. I think he's got a couple of the sizings wrong on that site. You can see the 30 and the 34' are both apparently 8 x 4'9" sections! But if you go up the page both the 25 and the 27 should move down, so 7 x4'6" is for the 31' (30 on that site).
What problems you having with Gardiners site? Having no problems this end 
Yes I noticed that some of the listings are wrong. I think someone must have done copy/paste and forgot to make the relevant alterations.
As for the Gardiner website, I keep getting the page where it says:-
The page cannot be displayed
The page you are looking for is currently unavailable. The Web site might be experiencing technical difficulties, or you may need to adjust your browser settings etc etc.
I've tried changing things around. The problem is definitely on my computer too. It's not my browser settings as I've tried 3 different browsers. It may be something on ZoneAlarm or perhaps the Windows firewall that I've tweaked wrongly at some point but I've checked everything I know and I've asked for herlp on newsgroups to no avail. Sometimes, my attempt to access the site causes a default to Google instead.
I've run this O/S since 2004 without a re-format. Maybe it's getting near time to clean up the drive and start afresh.
