I've only played this great game for one week, but so far I found that I've always gotten better deltaV when using liquid fuel rockets instead of SRBs where I had them. This is mostly intuitive though, I've only recently discovered the addon which shows technical stats even before lauching. Haven't been able to double-check this gut feeling, so I was hoping if you guys could share your experience with SRBs?

Off-topic, but since it's answered: where does one find the Engineer Redux?
