4 season versions usually have even worse ventilation, what with skirts and all. They are even more prone to condensation. Bring a micro fiber towel to dry your stuff a bit before packing up in the morning.
I think the weight savings for titanium pegs are tiny, just bring aluminium ones. I like the MSR ground hog style type, get a clone at aliexpress. The tents i mentioned earlier are freestanding, so no pegs needed, if it gets very windy, just make some wooden pegs from a few branches.
