most who have them would recomend the gardner slx which is a 30ft pole i only have the 25ft version but it is brilliant the bad news is alex doesnt have any in stock and wont have for a few weeks.
other decent pole is an xtel in that like the slx it is in short sections but this is more whippy than the slx and doesnt wear as good, brodex have brought out a new range of poles and ionics have brought out a pole called glyder but i havnt seen these yet so cant comment.
