I would most definitely use “Transfer with Sound Restoration”. 30-year old recordings, even when sealed, have many imperfections that can be eliminated or considerably reduced by our Sound Restoration process. There is also the “Both Versions” options. Most people in your situation (with your dilemma) order Both Versions. That way they will get both; a CD that sounds EXACTLY the same as the vinyl record, and a CD with Sound Restoration.
"I received the cds today and I can't thank you enough. My Mom just passed away and hearing her voice talking to me when I was a baby was so special. We also are going to be sending you a few homemade records that we've found. I'll let you know when they're in the mail. Thank you again,"
