The Kayakpro EZ-Vee works extremely well for kayaks. The bar doesn't telescope, but the saddles can be moved, so same difference. The saddles fit the profile of my kayaks well, a couple of tourers, an SOF and a Struer. I do add pipe insulating foam to the saddles.
Per the comment below, kayak weight is not an issue - they are very strong, the EZ-Vee has an x-shaped extrusion inside the tube and welded construction, nicely done. The Goodboy racks are pretty good too - less expensive, bolted, not as finished-looking and hold the boat several inches higher.
In action (7 years and going strong, no problems):
These racks are easy and fast to use, very secure and the boats never move. FYI I am a mechanical engineer and fussy about hardware and such.
