It strikes me that your right hand isn't going to get much of a workout with instrument 1. It will be useful for practicing left hand fingerings though.
You mentioned sweep picking in an earlier post. I don't know if you were joking, though, as sweep picking seems pretty far from the blues.
Paradoxically sweep picking does rely on a lot of left hand technique, particularly, eh ... I don't know what you would call it exactly -- I've seen it called a 'lay over'. Frank Gambale (the sweepmeister) calls it 'the rubber stamp'. It's playing notes on the same fret with the same finger by rolling the finger. So if you wanted to play E on the B string, then A on the high E, you could play them both with your first finger by rolling the first finger, so the E doesn't ring into the A.
I tend to think Frank Gambale has made his left hand fingerings harder to make the right hand easier, as it's the right hand that is usually the limit on fast playing.
