Thanks for the review. Did you figure out a way to seal the spindle or just dealing with it?It is ok. For not wanting to add alot of weight it is a good option. I am not impressed with the spindle or the seal on the top and bottom of it. I took it apart to check how much ingress of dust and moisture got in and it was alot. For it being pretty pricey (but not comparatively) I was disappointed in the shipping. It was literally poking through the cardboard and the main tube was bent. If i was to do it again, i would order the weld it your self kit so i could change the spindle.
As far as sturdy ness and construction, no complaints. My wife hates that it blocks the camera, but that can be fixed.
