Sorry maybe i shouldnt have said 'dont'!!
But it depends on what you're carrying mate. If you're around 70-80kg (i'm being nice with the weight

)and theres 2 of you thats approx 150kg lost there...
Then poles, reels,pumps, maybe ladders, trad gear,maybe backpack/trolley etc....with only 200kg to play with....not saying you'll be over, it'll just be close thats all
