ASW 27 wing tip wheels

Does anyone have experience with wing tip wheels on an ASW 27 ?

I am thinking about installing wing tip wheels on my ASW 27 (actually about 6-9 inches inboard of the wing tip). I was wondering if anyone has done this and how did it work for them. Did it change the handling characteristics? I am willing to accept a small decrease in performance (I expect it to be too small to notice).

I've made 3D printable tip skids that screw into the existing tips skids - once you've filed a flat spot on them and then screwed in a couple of nut inserts into the existing, flattened tip skid. They accept a rollerblade bearing as a wheel which can be replaced if they get worn. They are two-part so you can have the attach bolts be captive, requiring a smaller Allen wrench and smaller hole in the skid. They are also left and right handed - canted a few degrees outboard so the wheel rolls flat when the wing is tipped over to the ground.

Here's a link to a screen shot of the CAD drawing. These are presently installed on two ASW-27B's
