I am planning to buy BIAB 2018, which I have never used before. I am recently retired and am looking to significantly improve my guitar playing skills. I've played guitar most of my life. I also have been playing mandolin for about 10 years. Most of my playing is at home. However, I also play both mandolin and guitar in a contemporary worship band at church a couple of times a month. My goals include:

Improving my fretboard knowledge (I am also working through several music theory books right now)

Adding backing band accompaniment to my solo playing to add structure, improve timing / rhythm and add a fun factor to my playing

Significantly improve my jazz guitar skills, which are pretty basic

Improve my country jazz / swing skills by playing in a band context

Improve my blues / jazz / country soloing skills by playing in a band context.

Produce lead sheets (and sample music tracks) for use by our worship band.

I am planning to by either BIAB 2018 Pro or the MegPAK version. My question is: is the additional content included with BIAB 2018 MegPAK worth the additional $140 over the Pro version?

Any input you can provide will be appreciated!

Thanks!
