Have they changed the tarp specs? It seems to me the weight on my Explorer UL diamond was ~ 11 oz( 312 gm ?) though I can't find specs at HH site. But I'm fairly sure that is right, as I remember my 13 oz MacCat DLX was a couple of oz heavier than my stock HH diamond. ( but I think the newer ones are 3" longer, so I they would be a bit heavier also, but I an surprised at ~ 5 oz increase) They list the 30D Hex as 19 oz/530 gm, which is about what mine actually is.
Anyway, I have found that do be a nice tarp, for about 8 oz more weight than the my stock tarp. WAY more coverage. Which can be nice for hanging around on a rainy day, even with friends coming to visit! Look forward to your evaluation.
For I consider that the sufferings of this present time are not worthy to be compared with the glory that is to be revealed to us....that the creation itself also will be set free from its slavery to corruption into the freedom of the glory of the children of God. For we know that the whole creation groans and suffers the pains of childbirth together until now.
