I'm in the 255 camp and just tried a simple experiment.

From TSO issue the Edit command:  E T(ABC) CL

This opens the old editor on dataset t.clist member abc and after adding a few 
records and saving I checked the dcb which was VB,255,3120

Not the ideal blksize but the lrecl is what I expected.

Subject: [EXTERNAL] LRECL=255 vs LRECL=259

My whole life I have seen variable length CLIST/EXEC libraries allocated as 
RECFM=VB w/LRECL=259. Clearly, the intent was to allow up to 255-character 
source lines.

At PSI, we provide the option for customers to allocate our CLIST/EXEC 
libraries either RECFM=FB w/LRECL=80 or RECFM=VB w/LRECL=259. One customer 
claims the industry-standard for RECFM=VB CLIST/EXEC libraries is LRECL=255 
rather than LRECL=259. LRECL=255 would allow for only 251-character source 
lines, which seems rather strange to me.

Of course, my personal observations and experiences provide nothing more than 
anecdotal evidence. Like a man with two watches being unsure of the time, I am 
now unsure if LRECL=259 is widespread practice or if I was observing only 
outliers.

Any insight would be appreciated...
