Going with the LINE 6 - POD HD PRO RACK UNIT, is a great idea. Some prefer to use the LINE 6 - POD HD (Bean Format) with the DT 25/50 HD as it's less gear to move etc. Having compared the LINE 6 POD HD PRO RACK UNIT & POD HD PRO X RACK UNITS in live performance situations, it becomes apples to apples, when deciding which tones will get you through your live gig, both are more than up to the job. If, however you are a studio tone chaser, the extra processing power of the HD X, might be an answer. For my needs, I didn't end up purchasing either of those two units. I went with the LINE 6 POD X3 PRO RACK UNIT, I use it to record most of my bands songwriting. Even in 2018, it's still a powerhouse, live or studio!
