Ok I am playing sweet little angel- bb king There is a live version where you play 9 to 11 on b string and one where you 13 to 15 g string then 14 to 16 on b string? Will I matter which one I use? I am not playing the live version
Use the one that you think sounds best.

well they sound the same the only difference is on one theres a D# added and on one you bend to d# so im not real sure when I listen to his songs though they sound diffrent0.o
Is there one that comes more natural? Which one fits better? Can you add expressive techniques into them, if so which brings out the most 'expression'?

Of course, this is only if you're really critically thinking about. You probably aren't, so go for the one that is easiest and just feels right.
