I have been mulling this over. Possibly considering the stem below that has a 35 degree rise. An online stem calculator says that will give me an additional 1.7 inches of rise. That should be just the right amount and I can save my money for something a little more solid than an adjustable stem. Maybe I'll be sorry for not trying adjustable first but I'm thinking this is a good solution.
