If it works for you, great, but that's a fairly small size guitar. It's not going to project much. The LG-1 I have is an OO size and it can be hard to hear next to anything bigger, especially a jumbo. For finger picking and recording the OO is likely where you want to be.
Here are some sizes I ripped off a website:
Parlor: A light, focused and balanced sound, in a smaller overall size for a guitar
O: Balanced tone and response, slightly larger than the parlor guitar
OO: Has a solid mid-range register, great all-around guitar
OOO: Largest of the medium sized guitars
Dreadnought: The most common type of acoustic guitar, versatile for most players/ styles
Grand concert: Similar in size to a classical guitar, tapered, narrow waist to deliver a well-balanced mid-range tone
Grand auditorium cutaway: A great middle ground for volume and playability, cutaway for higher-neck playability
Jumbo: Large body with maximum resonant space for more volume and bass.
