I think the film cap is what I'd use. They generally can take more abuse than a lytic anyways, and that's a low value enough.

you can get a polypropylene (PP) or metalized PP cap at that value easily.

Only drawback is the price. That will cost you about $2 minimum for one cap, while the lytic is more like 1 buck for a bipolar.

Also, the leads of PP caps tend to be shorter, so you might have to look for one that has longer leads or get a polyester cap with normal leads (the red kind) as that will be better than an electrolytic in that place anyways.
