No "Intent" in interference

[DaveASA/FED]

Ok, I heard you all talking about it, but I just read the rule changes, haven't gotten 2007 books yet, about ASA change to take intentional out of interference. I understand there is still the untouchable response of "In my judgement there was no interference" but in this situation:

R1 on 2nd R2 on 1st shot to F6 handles it but traps it, bobbles it and goes to throw to F5 who is standing on the back side of the base allowing the runner full access to the base (no OBS is my intent in saying this) and F6 lets go a screamer from her knees toward F5 which is about knee high to the outfield side of the base. Right after she lets go R1 starts a beautiful hook slide toward the outfield reaching out with her left hand to hook the corner of the base toward home as she starts the slide the ball contacts her helmet and goes flying into the fence.

Under 2006 rules I have an easy, there was no intent to interfere so there is no INT, easy conversation with coach. But this year how can I say she didn't interfere? F5 was in position to recieve the ball, F6's throw was on track, R1 was performing a normal baserunning (assume the team has been hook sliding all day) activity. IMO I have a real problem calling INT on the runner in this case. BUT I can see some ugly conversations with the coach, about how can I say she did not interfere when the ball ended up at the fence. What have you all thought to say to the defensive coach in a situation like this? Don't get me wrong I have no issue in saying "IMJ" and going with it, but I just feel like this removal has weakened our rule support on this issue. Am I missing something???
