According to Zainasheff about half of your dry yeast will die if you sprinkle dry without rehydration.

According to my experience, which is worth at least as much as anything JZ has ever said, you won't notice any difference between sprinkling the yeast directly on the wort and rehydrating. ;)

I also agree with tDS - just add a little more yeast if it freaks you out. Or rehydrate if you really feel you need too. But side by side batches have proven to me that there is no difference in flavor - at least not on beers under 1.065.

Good to know. Seems like somethings are not as fact as they seem.

Fwiw I mean no disrespect to jamil. He has been a disseminator of great information. But if you have the means to experiment, it's always best to find out for yourself. It may be better to rehydrate in higher gravity beers (though even there I have not had bad experienced sprinkling directly on wort and maybe over pitching about 10-20 %) but side by side on IPAs 1.065 (ish) I have not seen any noticeable difference.

I like to rehydrate if I'm using dry yeast on wort > 1.060.

Thanks all.
Because the wort is gonna be >1.065, I'm gonna re-hydrate 2 packets and pitch them both.  Again, this is not my choice of beer or methods but I don't have time to get new yeast ordered (would usually use 1.056 instead) so I'm gonna use my emergency dry yeast.
I'm also gonna do a back up 5 gals with a good pitch of WLP007 but I want the remainder of the WLP007 for some English IPA that is on the schedule for the next day.

Interestingly, on page 8 it expressly states that rehydration may be done with water or wort!  Secondly, none of the recipes on the site use S-23 - Denny would be happy to hear that!

I've always felt that my rehydrated yeast had shorter lag times. What really helped when rehydrating was using boiled tap water and not purified, RO or distilled.

I'm inclined to go with the pro brewer's experience tho. ;)

I also saw that none of the recipes use K-97.  I've never even heard of that yeast.  The only character info on it is "fruity."  Anybody ever used that one?

This page indicates that it's good for Belgians or wheat beers with low esters.  So that seems contradictory to me.  Fruity, with low esters?  Weird.

I'm not a pro brewer...I'll go with my OWN experience!

Well I'll go by my own but I don't brew everyday, but the sum of my experience is very small compared to the major's.

Well, it's hydrated in boiled tap water and pitched into a 1.070 wort so we will gain some experience now.
