Good buy if you will use both sets at the same time
Roto Yellows are very good sounding strings and endorsed by no other than Guthrie Govan. This Double Decker 2 Pack is good value but take note that the two sets are not in separate packaging. So if you are only using one set, the other set will be unprotected unless you put it in a sealed plastic bag.
Good sound and feel
ConsBoth sets share the same packaging
