There was always a better solution than Wedekinds.
See Figure 4. Buy 'em from Schempp Hirth dealer. I've seen guys make their own too (the Schempp Hirth ones are better).
Easier to install, easier to assemble, easier to inspect the assembly. Not that I expect anyone who's spent a thousand bucks on Wedekind sleeves and installation to agree.
