I know this has been discussed ad nauseam, and I know i should have first tried to search more before I beg for help, but my brain doesnt want to think about filing my own bikes after fixing others' all day. Anyway...

Im building some king r45's on reflex rims 32h x 2 cross with revolution spokes. calc. came out to 292.2 for the front so I rounded down and found some 291mm spokes in my house (saving me $$$). I could have used my 293mm spokes but I like to round down. I rounded down 1.2mm.

After a careful build process I have a perfect wheel which feels about at tension, but a vast majority of the spokes have about 1-1.5 threads exposed beyond the nipple. some spokes have no threads showing, as well. the wheel is PERFECT in every other way (super easy build up), but will these exposed threads be an issue? I know you need the threads of both the nipples and spokes to be engaged as much as possible , but does anyone have experience enough to say that 1-1.5 threads not engaged will not be an issue? If it is I can man up and buy 292 spokes

Two considerations: I weigh 135-140 lbs, and these will be a race only wheelset. (those facts notwithstanding, I want this wheelset to last me a while barring any crashes)

Thanks
