but if srb\'s are a good kickstart, wouldnt liquids be a better kickstart? i just ran a couple quick tests, and it seems to me, SRB\'s are not even better than liquids dollar for dollar. i dont know that space shuttle...is it something i can download, or see the specs and rebuild it in KSP? i can see SRB\'s being useful if you only need one or two to get off the ground...it might be cheaper than going liquid, and if you dont have to spend the money, then dont, i guess. this seems like a very situational purpose though, and for 3 SRB\'s it seems 1 liquid engine and a tank would be far better.
