41005/9901 makes for a fairly easy to drive setup and super easy to tune,41001/9901 makes it agressive and quite punchy. 41021/9901 gets a decent runtime but feels a little flat. 41001/2096 i really like but gets a little less runtime than the 9901 setups.
my buddy has the 41021/2096 setup on his in buggy and it seems to tame it down quite well to run in buggy
