In the past few weeks I tried the Hexamid Solo with Serenity Net Tent, on the one hand, and the Hexamid Solo Plus with the new, updated Hexanet, on the other hand. I added the optional beak in both cases. I loved the weight and simplicity of the Solo & Serenity Net Tent, but after sleeping in it for one night I found it a little small for my taste (I am 5' 11" tall and around 185 pounds). I did fit in this combo, but there really wasn't any extra room, and head room was tight for sitting up. I also felt that wind driven rain could be an issue for this combo due to a lack of any meaningful bathtub floor on the Serenity Net Tent, although I never experienced any rain. So after some consideration, I ordered the Solo Plus with the new Hexanet, figuring I could return either combo after comparing them. The weight penalty for the Solo Plus/Hexanet is about 1 ounce for the Hexanet and .8 ounces for the Solo Plus tarp. There are also six additional stakes required for the Solo Plus/Hexanet combo, four for the Hexanet (which must be staked down) and two for the additional side guy lines if used. (It is worth noting, however, that the Serenity Net Tent was significantly roomier at the ends with a tauter net if you staked it out, although it worked ok just clipped to the corners of the tarp.) After setting up the Solo Plus and Hexanet I knew immediately I would keep it over the Solo/ Serenity combo. The Hexanet is substantially roomier than the Serenity Net Tent (36 inches wide vs. 26 inches wide) with several inches of additional head room at the peak, with a 7" bathtub floor that appears to provide almost complete protection from wind driven rain when pitched under the Hexamid Solo Plus. The Solo Plus does have a slightly deeper footprint than the Solo version (62 vs 54 inches), but the length is the same (9ft for both). For me, the minor weight savings, smaller footprint and simplicity (less stakes) was not enough of a benefit compared to very substantial increase in usable space and weather protection I believe the Solo Plus/Hexanet combo provides. Just my thoughts based on minimal usage so far, and YMMV.
