Hi Keith,
I'm sure you know this, but this statement seems to imply that rib lacing and gluing could be an either/or proposition. That's not the case of course... you need to glue the fabric to the cap strips regardless of if you lace or not. I would strongly advise lacing also, as it really takes very little time in the grand scheme, it doesn't look bad at all, and it's a definite safety improvement. It will be more desirable to most buyers also, IMO. Is the "RV7" mentioned actually a RANS S7?
