Thanks Andy,

That's all good input, thanks. I especially like the sight tube idea. Very novel. And that may be the most useful in this instance as I was suspecting that the alignment between the fork crown/ fork blades ....and the steerer tube...may be the culprit. In other words, I think everything from the crown to the dropouts is OK but suspect the steerer is a bit tweaked in relation to the fork crown. But, I'll run these test to see how well everything lines up. Thanks much.
