You're correct: 90-95% of RHop performance for SO much less work and fiddling. The most modern Maple Leaf design is going to be the MR.Hop, which would be my recommendation.
My choice would be the 85 degree silicone MR.Hop, given that silicone is so much grippier than rubber, even at harder durometers, so you get the advantages of a harder rubber without the real disadvantages. Don't get the softer versions, as those tend to be too soft and too sticky.
The PDI W-Hold is a lot older, simpler, and has less hype around it, but I really like it in lower powered setups, so that's an option as well.
