For guitarists who are always on the go, which often describes the larger segment of guitarists out there; owning a portable guitar is something you may find necessary. Large guitars can be somewhat an encumbrance to carry and might not really give you the comfort you would like when moving from place to place. Not forgetting that large guitars can also put some weight on your back making it quite onerous to travel freely while carrying them.
However you certainly are not out of options. For instance you can choose to go for you rock midi guitar at guitar center. This is a rather medium sized guitar that is not too large, of fair weight and guarantees easily stress free portability.
