My Brompton M shaped handlebars have less length for the grips than standard.

With shifters this length is even shorter. Also the stock grips also appear to be shorter than standard.

The stock grips are now a bit loose fitting (from use I guess) and tend to come off slightly when riding. So they need to be changed.

I am also considering getting bar ends. These will shorten the available grip space even more.

I can move the shifters and brake levers inward a tad bit to give me more room.

But I am afraid the standard grip sizes may not fit, and so I am pondering bar tape.

How does bar tape compare with proper grips? Can they be as comfortable? Do they come off easily if the handlebars are held on tightly? Pros and cons would be greatly appreciated.
