Fancy Fuse for Regenerator?

I'm thinking of putting one of those SR Purple fuses into my P10 Regenerator. I'm  seeking opinions if this is a great place because the benefits will go to all my equipment, or if it's a waste because the power is regenerated anyway. Please don't respond if you think these expensive fuses are all a joke, as I'm not trying to start one of those downward spiraling threads. Thank you.
