1st off, before giving an opinion on which you should get, or which we would get, what kind of temps are you looking at using it in, what range? Will you ever go below 20F? Or, even below 30F?
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.
