I hate to bring this back up as it is pretty old, but I have questions. Generally speaking, what the difference in spool characteristics between a 14411 - 75F00 ball bearing and a 14411 - 75F00 brush bearing? Other than the ball bearing is gonna spool quicker. Is there really going to be much of a difference in how long it takes to get to full boost? I also have a question about this serial number: 466543 - 1C -obviously brush bearing, no divider, but I can't find anything on the 1C. Any ideas?
