I think the first questions involve:
Do you want/need your tent to be hiking pole supported or come with tent poles
Do you want/need double walled tent or single walled?
Do you want the lowest weight shelter? There are two or three shelters in the 15 to 18 oz range, all hiking pole supported and constructed from CF from Zpacks and others, and if you want to combine a tarp with an inner net tent, Mountain Laurel Designs,
What is your budget? Which IMO is the same question as do you want a cuben fiber tent for the two or three additional ounces at a premium os $XXX per ounce
How much headroom do you want?
Have you rent Ryan Jordan recent review of the REI Quarterdome SL1?
There has been a lot of excitement around Dan Durston’s tent available from MassDrop.
TarpTent makes excellent products. I love the headroom and the length of my Double Rainbow but I would probably take my MLD Grace Tarp on a trek where I expect strong winds/rain.
