I'd say yes, depending on how much yeast you have in suspension and how you go about kegging it. If you rack top down and it taste good currently, i wouldnt bother, If you rack from the tap and it tastes on the upper end of yeasty, id think about crash chilling it. Atleast for 24 hours. As when you keg/bottle it, you will drag a whole bunch of extra yeast from the cake into your keg. Making it yeastier than you desire. Another option would be to ramp up your temps at the end of fermentation to induce the yeast to finish up and then see if they naturally flocc out.
If you have a filter, you could always filter it and then do an add back of yeast with some unfiltered beer left over in the fermenter! :lol:
The next weizen i will do i will proabably filter as a krystallweizen, just so i can see if the beer profile is as i desire. Then do another of the same recipe (if its good) unfiltered just to compare.
