I whip lines. But then I also do my own splicing. My skills are degrading since I don’t have a sailboat and the opportunities to keep them up are less.
I rarely will use a stitched whipping and will just do a wrap and bury as Lepke mentions above. In over 5 decades of boating, having one of my whippings fail is extremely rare. If a 10 year old whipping fails, it takes me all of 5 minutes to redo it (that includes the time to dig out my rigging bag and get the whipping and a knife).
For those rare times when I want to do a stitched whipping, I have taken to using this method instead of the more traditional method. It works great on double braid.
