Belgian Rock Candi v Belgian Soft Sugar

[Cloud Surfer]

I’m going to use either of these two sugars alongside some D180 syrup in my next Belgian Dark Strong Ale. I haven’t compared these before, and guess they will be very similar. The Rock comes in a darker grade than the Soft.

Can anyone shed some light on the differences, if any, I’ll achieve using either of these two sugars?

I've never used either, but I would assume that the soft will dissolve more quickly/easily than will the rock.
