Singlespeed & Fixed Gear - paul hub deep v spoke.... help

im wondering if anyone who has experience building paul high flange track hubs to velocity deep v rims can confirm a spoke length. i calculated that ill need about 281 (but dt and wheelsmith only have the 282 in spokes i want) so im wondering if anyone can confirm this number. its a flip flop hub so its all good to go. even at employee discount a box of spokes will cost me like 50-60 bucks, so i dont want to screw up. my parts and truing stand and alignment gauge and spoke wrench (all at discount, no less) are going to almost cost me about what i initially spent on the bike. i want to build some really strong wheels, if someone thinks i can get away without using double butted spokes please inform me. these will be only my 2nd and 3rd wheels every built so im kinda new to this. thanks a bunch. and please no bs numbers. ill be so pissed if i order the wrong damn spokes cause i trust some ******bag. so dont be a ******bag

i used 280mm dt swiss spokes with no problems... didn't i just answer this exact question 2 days ago?

yes, yes i did http://www.bikeforums.net/showthread.php?t=444095

thanks, you probably did, but i tried to find my old post and it wouldnt show up for me to look at. i return to work tomorrow so im going to order spokes and i had no time to wait around and think and screw around on my computer. also, what exact spokes did you use. like competition, champ, revolution, straight gauge etc. thanks

competition spokes

i got 282 spokes and i unsucessfully tried to build a wheel tonight. i wasnt exactly sure what i was doing, the book by park tools which i used was kinda confusing. the big problem was that when everything seemed to have been done, all the crossing spokes on the right side were WAAYYYYY tooo long- i say that modestly too. did i get the wrong sized spokes? should i have gotten 280's or is it possible that i just built the wheel wrong? thanks a bunch

you prolly just built it wrong.. unlace and find a wheel prebuilt in the same pattern to copy.

did you follow this? http://www.sheldonbrown.com/wheelbuild.html
it's pretty idiot proof...
