Hmm, rereading this and feeling that Im coming off as a dick, and that CW is offering ideas (in his way); somehow that led to the Adams Family... So lets get back on track.
Disregarding everything else that's unrelated to the rear (driven) pulley (including the clutch and its price), how big is the benifit to switching to angled slots (from stock str8) IF i have no hills, current issues with accel., and pleanty of power from displacement alone? While this has been addressed generally in the past, there seems to be no consensus. Please assume everybody has an equally advanced understanding, and awe us with your knowledge (open to all btw, not just CW). Theoretical explanation and/or experiance preferred.
