It all depends on how ready for action you want to be i suppose , if you think you can get by with the one pole go for it , as you will see , i like to be ready with a back up plan [ unlike Sven ] , i have a pole for every occasion , all 3 cost me about £500 , i did pay over the odds , shop about and you will get them at a better price .
If one breaks i use the other , ok the orange pole would be a right arm ache on domestics but at least i wouldnt be stopped !
