it should fit but why go bigger? Whats the break strength on the 5/16 vs the 3/8?
It is worth it in my opinion tho go with the 3/8's. YOu could fit 25 more feet on with the 5/16 but you loose quite a bit of strength.

Our Viking Trail Lines are rated at 13,000 lb (4,6 metric ton) for the 5/16" and 19,600 lb (6,2 metric ton) for 3/8"
13k is strong but another 6.6K is nice! Especially since you are only giving up 25 feet of line. Not to mention it is more material. If the line cuts or gets frayed a bit it just gives you more material to work with.
When I had synthetic on my Mile Marker it never melted during some heavy winching BUT I always worried about it so the heat resistant thing would be a nice piece of mind.
Long winching can generate some heat but the biggest problem would be if you needed to winch yourself down something. for example, you are in a bad situation and you need to winch OUT using the power of the winch. There is a brake ion there (with this type of winch) that makes the winch get REALLY hot REALLY fast. It is not too often that you would be in this situation but, if you ever where, the LAST thing you want to be thinking about is your rope melting!! lol.
But really, the prolem with heat is over the years of winching the heat will break down the first couple of layers of line. Especially with this type of winch that tends to get pretty warm. Then one day you need to winch with the full length of your rope and that strength just is not there any longer.
While you are recovering, it is usually not just on flat ground pulling a light rig, otherwise you would have just used the strap, right? In my experience, a lot of the time the winch is out, it is some crazy situation, somebody off camper till it is winched up and with tons of weight on the line. I just take the position that when it comes to winching it is good to have strong, new equipment not only for saftey but for peace of mind. Especially while your rig is hanging half way over a ridge and your almost there, almost there!!!....
