Yeah, but that last 1% might give you a tiny fraction of haste more, so although it might be worth gearing for, it might not be when you are talking about swapping from:
Turban/Rap Harness
+1.18% True Haste (3/256 more than the below build)
-VS-
Skadi/Mirke Hauby
STR +5 DEX +9 AGI +9
Attack +16 Ranged Attack +6 Accuracy +10
I think the 2nd one wins, personally.
See below for math.

Notes on results:
You actually have to do the math yourself for each haste item to find out what the correct increase will be going from 25 to 26. Basically, you have to find the xxx/256 value for each item by multiplying 256 times the listed haste value and dropping the decimal (that's where you get shorted). Next, add each item's real value in fractions, then compare that total to the correct 25% total which if all things are correct would be 68/256. Here, let's do it with the proposed gear (I'll do the entire process on turban just so you see what I'm talking about). Note that some values of Haste may land just right so you don't actually get screwed out of any:
Walahra Turban +5%*256 = 12.8/256 (drop decimal) = 12/256 4.68% True Haste
Rapparee harness +4% = 10/256
Speed belt +6% = 15/256
Dusk gloves +1 +4% = 10/256
Homam pants +3% = 7/256
Homam feet +3% = 7/256
Airy Buckler +1% = 2/256
Skadi's Visor +3% = 7/256
Wyvern Earring +5% = 12/256
OK, so let's add the top values and see how much haste we get from the originally proposed gear.
15+12+10+10+7+7+2 = 63/256 = 24.61% True Haste (A 2% haste item would make up the remaining 5/256, exactly.)
2nd Set
15+12+10+7+7+7+2 = 60/256 = 23.43% True Haste (A 3% haste item would get you 1/256 short of capped. 4 x 1% items would get you capped exactly. A 4% item would get you capped with a few fractions wasted.)
Compare the above to, like, monk with their insane belt:
5% Turban
5% Byakko's
12% BB
3% Fuma
30+12+12+7 = 61/256 = 23.8% True Haste (A 3% item would cap it exactly.)
Note that due to how the difference in item fractions means the 25% THF swings slower than than 25% MNK, at least as far as haste from gear is factored, but then again that thief could drop Skadi and go back to Turban for even more haste.
At any rate, it's all very interesting but either way, let's just hope our thieves can get in a position to put any of these in practice, eh? :D
EDIT: For THF, it seems you will need more than 26% to reach cap. Looks like 28% is the number, if I have this math right.
