I have a 65% density front and use walker No shine which does a decent job but under certain lighting conditions I reckon you can see a bit of shine..maybe you can try smudging some glue over the tape to avoid the shine.. The St-30 has a bit too much shine for the front so I'd try to avoid it if your density is on the lower side. Good luck mate.
