Good info, gents, and will take these points back to my association. Not sure where the line-straddling momentum came from - likely from the U3 and then got liberally transferred to U1.

I've always stayed about a step foul when there is a runner being held on first. The only time I've ventured near or on the line is the R3 situation if my view is being blocked, usually depending on the size of R3.

Thanks again.
