I once lobbied for Plasma Bolts...
Yet I think plasma bolts would diminish the flavor of SFC's plasma-chucking races. Perhaps if Plasma moved at speed 32 (instead of 36), bolts might be necessary to compete. But the greater issue regards regular combat in SFC...combat between all-too-common BCH's, CWL's, DWL's and other elite ships. If players usually flew ships with far less impressive power curves (e.g. Fed-CA, Klink-D6), plasma would truly show its strength in SFC.
In an environment that permits battle groups comprised of three K-AD5's or H-APA's...yeah...Plasma Bolts are beckoning...but are they truly needed? Hmm.
SFB's Enveloping/Shotgun Plasma torps would lose their extra energy if bolted. So a 100-pt Enveloping-R torp would be treated as a 50-pt warhead, which could do 25 points max, assuming it hit (66% accuracy up close, subject to ECM, Erratics).
I never bolted Plasma in SFB. It just wasn't a good return on the investment.
