List of aftermarket helix angles


977TP anyone? No name on it. Almost looks like a Bender number, but only 3 numerals instead of 4.
 
maxx perf I believe 6pt5? Looks to measure 46-31? anyone else had one or know angle?
 
What does the PROGRESSIVE portion of a progressive helix mean. Take for instance a 48/42. Does a "progressive", start at 48 and finally end up at 42? Verses a standard that keeps a 48 degree till half way then change angle to a 42?
