I can't decide which Jackson to buy, the RRXMG:

or the new X series Soloist, SLXFMG: http://www.jacksonguitars.com/guitars/soloist/models/soloist-slxfmg-rosewood-fingerboard-transparent-red/.

Both are pretty similar in specs (active EMG 81/85 pickups, compound-radius rosewood, 24 frets, etc), but of course each have their own pros and cons:

Cons for RRXMG: May be hard to use sitting down (I've also read about a fret buzzing issue)
Cons for SLXFMG: Very new guitar and I can't find any reviews for it. This guitar also has AAA Flamed maple top veneer. Is this cheap??

I should note that I'm a huge Metallica fan and will be mostly playing their style of music, among other heavy metal styles.

Any info on this would be greatly appreciated.
