Which pivot points with higher time frames?

I have a question regarding which pivot points to use on which time frames.

If I am trading using the weekly chart to find support and resistance and zooming in to the daily and (minimum) 4 hr to find entry points would it be better to just use monthly pivot s/r levels or should I include the weekly levels?

It seems to me that on the daily chart the weekly s/r levels are only valid for 5 bars before the pivot levels change. Saying that though, sometimes it appears that price does react to these levels during that week.

Does anyone have an opinion on this? Thanks.

Doesn't it make the most sense to use the same pivots on all the timeframes you're looking at? I prefer the monthly and weekly pivots so I have them on all timeframes from weekly (trend) down to M5 (scalp). It's still the same price (pivot) zone. All you're doing is drilling down to progressively finer slices of time.
