I still have the standard tips, which have a downward skid, which are the same as you can see on this pictu http://aviation.derosaweb.net/dg101/...1RP_deploy.JPG
Would having the optional TN 301/20 wingtips/winglets fitted make a difference to this downward flexing?
No. Any small change in the last 10-12 inches will not change the twist that has been imparted of the last 10 feet of the wing.

Still very interesting to see that happen. Are there any other gliders that have this effect at higher speeds?
Almost all do, but to varying degrees. Modern ships generally have accomplished the aerodynamic objective by using airfoil changes toward the tip to get benign stall, and by having structures that a more stiff in torsion.
