I'd say it's worth a go if you feel it's come to the point where your control needs tightening up.
Do you carb count? I would obviously recommend getting on a course for that as they won't let you have a pump if you can't carb count first.
I was on injections for 12 years until I went on a pump, I wouldn't go back to it now, I only inject if my sugars are really high to bring me down quicker than the pump. since being on the pump though I've managed to reduce my HBA1c down to the 7's and combined with new diet I just reached the 6's at the start of the year so I'd say it's worth it as long as your willing to put the effort into it.
Have a chat with your diabetes team about the pro's and cons and see what you think, they might be able to show you one.
Good luck
