I bought a DD Travel hammock few weeks ago and have already spent few nights sleeping in it.
I would like to add some comments:
Regarding the DD webbing,
indeed it is much bulkier and heavier than a 3mm rope of a whoopie sling solution. What I don't understand though is why in all related threads people compare the DD's webbing with the bulk and weight of the 3mm whoppie rope only and do not consider also the tree huggers. I think the whoopies+tree huggers are heavier/bulkier than the DD webbing. The actual disadvantage I find with the DD webbing is that it is not as long as I would like it to be plus it stretches a lot if you use the whole length (one night I was sleeping in the hammock between 2 trees ~6 meters apart and in the morning I woke almost touching the ground - this did not happen though when I hung between trees that are close to each other, in which case not a lot of webbing is used).
Another minus I find with the DD webbing is that there are no specs available for its strength. I feel safer when I know the breaking strength of my suspension (although I know in practice many parameters affect this value).
I must say though that overall I am happy with this simple DD suspension solution (cheap, did not break so far and never read about any accidents in forums, and it served well its purpose until now for me). Adding a more advanced suspension in this hammock would significantly increase the cost of the hammock (the hammock, including the webbing, costs 49GBP these days, while a good whoopie sling suspension solution costs only itself ~20GBP). Perhaps it would be good if DD would offer two options: 1 as is now, plus 1 more expensive e.g. with whoopies)
Although I do not have a lot of experience in hammocking, for what I have seen until now, I must say that this hammock is really good stuff and on a un-beatable price (especially for us, the Europeans - I leave in Finland) .
I am very pleased with it so far!!
