^ very well spoken. O.P. listen to what everyone has to say, even if you don't particularly like their tone. There is only two ways this can go, you can listen to those who don't know anything about a rotary or you can listen to the die hard enthusiasts on here. Most of the enthusiasts will be a bit harsh in their sentence structures, but rest assured it is only to sway you from taking the wrong path. Either way, take heed to their knowledge. Most people learn from their own mistakes and go on to teach what they've encountered.
