Well, removing the jaggedness is easy enough:

#declare xShift = segPosA.x; // + ((rand(myRand)-0.5)*LSpike) + xPlus;
#declare yShift = segPosA.y + 0.5; // (rand(myRand)/5);
#declare zShift = segPosA.z; // + ((rand(myRand)-0.5)*LSpike) + zPlus;

The trouble is that all the forks then just go straight down. Is that what
you meant? (probably not).

The most significant params are LSpread and LSpike in terms of the basic
shape of the bolt.

Try these four settings:

//Make_Bolt(500, 11211, 0.03, 6, 0.3, 0.05, 0.5, 0.2) // normal (whatever
that means)
//Make_Bolt(500, 11211, 0.03, 6, 0.0003, 0.05, 0.5, 0.2)  // small LSpread -
quite nice!
//Make_Bolt(500, 11211, 0.03, 6, 0.3, 0.05, 0.5, 0.0002) // small LSpike
//Make_Bolt(500, 11211, 0.03, 6, 0.0003, 0.05, 0.5, 0.0002) // small LSpread
and LSpike
