Hey TJ,
As I mentioned in my other message.
I believe the rope is UV resistant (confirm it with masterpull) so winding up the extra 25' on the outside of the bumper shouldnt be a problem.
The rope is exposed to UV even while on the spool, so I doubt its an issue..

" SUPERLINE I Is the only synthetic
winch line that is heated and pre-stretch to
its ultimate strength. It also has a braided
cover that provides excellent abrasion
resistance and protection against mud,
sand, dirt and UV rays. Just another highly
innovative product from Master-Pull."

I would definitely Re-spool it better and neater.
Mine definitely doesnt look like that and I have the 10 foot rock guard at the end of it spooled up.
Guide it evenly on the drum and it should fit more, as soon as it starts to rub, back it off a bit and wrap it up.
If your winch is pretty slow, at least you've got a 25' head start on a pull..
