FTA here, with a few suggestsions.
- Even if you have not tended to have issues in the past, please follow the recommendations in the static document from FIRST.
- If possible, use the L-Com surge protector; if you can't, at least use a ferrite bead.
- This year, FIRST has officially recommended we use anti-static spray at events, although they are not requiring it. (In Illinois, we have been using it whenever possible, and it seems to be effective.)
(Also, my guess is that the weather is drier than it has been recently if you start seeing a spike in lockups and sparks-humidity greatly affects that.)
