On a recommendation from a friend, we went with the over the toe rail cover from the Canvas Store. We ordered it last December and got a decent discount. I was a bit nervous at first as I had read one bad review prior to placing the order. Although it's only been one season, we couldn't be happier with the customer service or the product. No affiliation, just a satisfied customer.
(although the link says "My Website", it's actually the Canvas Store site)
By the way, here's a photo of the cover on a Pearson 33 if you're interested
