Had a play with one today at the Swindon roadshow. Live in Swindon and it was raining so thought what the heck.
30' grafter was way to bendy at full stretch if you do lots of work over conservatories. (Swindon is full of them)
The 50/50 30' pole was much better but for the price I think the extel poles I'm currently using are far better value for money.
I thought the 40' glyder was a much better pole overall than the new grafters but way too expensive in my opinion
