What is the best hammock camping setup for 4 season camping in germany

what would be the absolute best hammock camping setup if money is not a problem

in the summer the highest temps would be ~20-24C (68-75F)

in the Winter the lower temps i would expect will be -10C (14F)

what setup would be the best in these temps i would hope that the hammock has a bugnet,an underquilt that is easy to remove / one thats always on like the superior gear ones but i dont know if that is a bad choice because it could get way to warm in the summer if i buy a hammock with attatched underquilt that is rated for -10C (14F) comfort rating. This worry is the only reason i did not buy a superior gear one already

and help or tips would be greatly apreciated
