Not been on here in ages, but thought I'd get your guy oppinion on the front kick to the head. (ala anderson/segal grin)

So I've seen this practiced (and practiced it myself) and it seems one of those techniques where a person may hold two opposing views.

View A - It is a technique not worth the risk of using as it:
Leaves you vulnerable to a take down
Is low percentage

View B. - It is a valuable technique as:
If it lands, it's seems highly likely to stop your opponent

I was curious as to your views.

As a side, does Silvas kick add weight to View B? Or does the lack of previous KO's of this nature in MMA (to my [narrow] knowledge) add weight to View A?
