Hi Dan,
nice to see you on here 

ya i would just leave the back alone,like they said if you scrape it smooth your violating the back and will need to back it.
i know you can make a sweet bow from it,just be patient and keep coming back and asking questions,and please dont forget those
ever important PICTURES,we love pics.plus they are a great benefit for getting the proper advise.
hell of a hog chad got eh?                keep coming back brother
                                                            peace,
                                                                    tim
