just out of curiosity, what are your reasonings for the tuning you have? specifically the MP17, Zwei and MW9?
are you worried about durability values? I'm assuming the Zwei and MW9 sit at about 12/13 durability at those tunes, correct? And the MP17 at that tune to keep the weight of the module from getting too high?
imo, I don't think that duribility should be much of a concern, if you're building this sv for online battles. If you haven't noticed already, you'll see that they go by pretty quick, I'm refering to the speed of your sv to take down other svs (and need to leave the arena to reload/recoup health) and the speed at which you get taken down and get dropped back into battle =S
Also, in terms of your option modules, might I suggest dropping the model 1/16 for another new sv plans, and the reinforced window for another wax hz and the O.C. TS for a pair of co-proces 640s? (personally, I'm starting to run mainly just wax hz and 640s/T.M.s)
*edit* the more I look at thsi build the more I like it, how about tuning the MP17 and the MW9 both to +99, and the Zwei to -99 and body to -28? I think that hsould be a difference of about + 4 tons (trying to do the math in my head right now, option module changes not accounted for either) you will probably need to adjust the legs heavy, but with the 4-baller you should lose too much speed, seeing as it's base speed is 206 km/h
*2ndedit* there isn't much o.c. breaking here, which could be a problem, drop the zwei for a -99 granat if that bothers you, though if you play your cards right online and keep your eyes open for the 2 on 1 oppurtunities

then o.c. breakage should be much of a problem.
Take the SV online and adjust it to your playing style, there's not better advice to get then experience with playing a build.
