I use a hop spider AND an inline filter before my plate chiller to whirlpool. Works very well, but I don't keep the hop spider in the kettle during whirlpool... If I'm doing a whirlpool hop stand, I'll get the temp to about 180F, do a 20 min stand, and then begin cooling again, as soon as the temp is below 150F (pretty much immediately), I pull the hop spider and continue cooling/whirlpooling.
Whether I'm doing a whirlpool addition or not, I pull the hop spider at 150F.
