Most slashing beams cause damage intermediate between "B" beams (or "L" in the Shivans case) and "S" beams, they are not "S" or "B" beams so they can't really be compared in the fasion of which you speak, there would need to be a "M" class of beams for that.
I never got the point of slashing beams.

Slashing beams?
Static Beams?
whats the difference?
Sorry i didn't use the special wecial terminology of terslash of bgreen.

It was my thinking people would probably know what the definition of static would be when applied to being the opposite beam would be (only goes one direction doesn't change trajectory).

In that terminology a slash beam could be considered a dynamic beam (goes more than one direction).
Yes there is a big difference between slash beams, i was more overly getting after principle of why the slash beam was persued.
Slash beams can damage more subsystems that are strewn about all over say a destoryer, by sweeping over it's target as opposed to hitting one spot only(like normal beams do).
THAT'S THE GENERAL PRINCIPAL BEHIND SLASHERS
As far as slash beams doing more damage than standard beams.
I took references from this thread
http://www.hard-light.net/forums/index.php/topic,39346.25.htmlWhere mars posted posted beam details.
Please tell me people understand at least the principle of the principle of slashers now

I don't know if what mars posted was accurate or not, but i'll take it as accurate, since nobody posted any solid details on beams like mars did.
Anyway, if i'm not showing off the difference between slash beams versus normal beams enough,
