Now he is
Looking at the two together (just bought the TW Hornet for his Christmas present) There is not a huge amount of difference in the general design but there are a few subtle differences that may make you sway more towards one rather than the other so here are my thoughts so far:
Overall design
Well, a hammock is a hammock and there are not a lot of different ways of changing that! Both the TW Hornet and the DD Travel/Frontline utilise the double layer base with a bug net for bite protection. The Travel from DD is the only one to boast a waterproof base but this impacts on breathability. The DD's also have a zip on each side of the bug net as opposed to the TW Hornet that I have bought, but there are other versions available with twin zips. The TW, however, has a zip to close the two base layers as opposed to a few bits of velcro for the DD's. There is also a softer feel to the material utilised to make the TW hammocks.
Space
I have not been in the TW yet as its my sons present but I have strung it up to check it over so there are no disappointments on Christmas Day. What I did notice was that the TW looks like its wider and therefore forms a deeper base in which to lay. This helps with getting that diagonal position for a good nights sleep. The net also stands much higher when rigged, and I reckon that I could quite easily sit up in there without touching the net. When it comes to the DD, I have used it quite a few times and slept very well indead. The more cramped conditions have never bothered me as I never knew anything different. The DD just
works
Quality
It looks good so far. The sewing is spot on, no loose ends or bits not done, durable multiple stitching on all stress points, in fact I can't find anything different between the two again. What I do know is that the DD so far has stood up to the use its had with no problems but the TW is still unused, only time will tell.
Other Stuff
The TW came with enough strapping, stainless rings and webbing to get you swinging from the trees. The DD comes with a little less but probably enough as you will soon be adapting it anyway! What did work for me with the TW though is a rather nice stuff sack that has multiple compression straps and enough spare room to put in a TW XL tarp and rigging with room to spare. The DD comes with a standard stuff bag but does not make it impossible to put the hammock back in thankfully. Both also come with ally tubes to spread the bug net open.
The Verdict
The TW hammocks really do look good and I may well get swayed in their direction when I get to climb in on Christmas Day. The DD is an impressive bit of kit and I love it to bits but I just have this little feeling that the extra space in the TW Hornet might make it a bit more comfortable, if that can be done. Either way you can't lose and TW have some lovely looking gear, I have bought a couple of the Sargasso Tarps aswell and these are half the packed size of the DD 3x3, but maybe a little less versatile for the moment until the sewing machine comes out again
