Anyone of "us" older bicyclists have any experience using Ergon handlebar ends?

When doing sustained touring using drop bars, I am now getting tingling and eventually numbness (as the tour progresses) on the first 2 fingers of both hands

After touring ends the tingling/numbness recedes and eventually disappears.

A FT member suggested that I look at Ergon bar ends as that is what he uses on his "straight" handlebars. The Ergons are expensive, but that is irrelevant if they prevent/reduce the tingling/numbness. Extra tape and gloves are going to be used too.

Thanks in advance
