I don't know anyone flying the CL350 at Netjets, but I do have several friends flying older CL300s in Part 91. They love the airplane - very capable with great performance and very roomy up front for longer flights to Hawaii or to Europe. It is well respected. I don't know anyone flying the CL300 with many negatives - but I am sure there are some.
Not sure about the CL350 at Netjets (hopefully someone will respond) - but I do like the look of those winglets!!!!
