When I was looking for some new good GRH builds, I also looked into the 5P sub forum (dont own it yet). When I saw the builds, I was saying to myself: Seriously, this standard build is missing? So now here it is: Alt with STD engine: Alt with STD 325 and less JJs
Updated the thread with a third build, so now we have XL 325 with 3 JJs and 37% cooling, STD 300 with 4 JJs and 34% cooling and STD 325 with 1 JJ and 34% cooling too. So a Wubmonster for everyone`s style. ATM I prefere build #2, because its durable and those 4 JJs are really worth the tonnage.
Just messing around in 'Mechlab. This is a LightEngine variant with max speed and high DHS (1 fewer than OP), but no JJ.
