The more authoritative the site becomes, the more immune it converts into, so since you said your site is pretty legit and steady in serps, getting few comments from relevant authoritative sites won't hurt at all, given that they moderate and weed out bad comments and bad neighbourhood links.

In all cases, do try to make a mention of your domain and wrap your link around with a relevant text, which match to both of your site and post topic. This shall provide some padding for your link.
