I think any improvement in results would be negligible. I have a John Deere 220E with a floating head, so it has a front and rear roller on the cutting head, plus the rear drum drive. I don't really notice any significant difference in its striping ability over my Toro Greensmaster 1000. With bermuda, I think you would be better off repeating the same mowing pattern to get better stripe definition... and just know that our bermuda will never stripe as easily as the lawns of our cool season brethren.
