I am sure this has been covered but didnt find......

I typically use disposable bags, but would like to invest in a couple of really large, reusable decorator bags... any concensus on which are the best bags?

Also, I would like to order a really large, round tip (non star) (bigger than any of my Wilton's) to decorate my cupcakes quickly... any advice on which brand and size to go with.

Thanks as always for any feedback!

For icing cupcakes I like to use Wilton's 2D tip. It makes a great swirl. Maybe you already have that one. I have some wilton featherweight bags. I prefer to use the disposable ones if I can. I hate washing the others.
