Shirley ... Like most things, there's pros and cons towards bagged vs. yard good battings.

First of all, have you used Hobbs wool battings before, to know if you like it?
If not, do you want to take the risk on an unknown for you?

What size of quilts, wall hangings, table runners, etc. do you make.
How much wastage do you have from bagged battings?
Usually there can be less wastage with rolls.
Are the bagged batts big enough for the quilts you make?
Or do they need to be pieced?
Will the roll be wide enough? Or will you still need to piece?

Bags can easily be moved around, and are easy to find storage in homes.
Rolls are weightier and bulkier, and sometimes can be darned awkward to move.
Let alone to find somewhere to store them in your home.

Do you want all your upcoming projects to have the same battings?
Or do you like different batting types according to the project?
Do you want/need wool batting in every project?

How long will a roll last you?
How long will the case of bagged batts last?

While Hobbs has a sale for you on both ... what price is each per square inch?
Usually roll battings are less per square inch. Maybe not?

Is the saving enough of an incentive regardless of which type?

I've given you some of the pros and cons to consider.
There's lots more, I am sure.
