obviously im in a much different area but went the heavier route and am very happy.
to be able to haul 3,5 metric tons while towing a chipper and still brake in a timely fashion.
i don‘t know if there is a company in sweden aswell but gefa (german) is producing bracing system with a wide webbing and buckles. available both static and dynamic.
i use it when there is not enough room for boa.
