As we can't post in Marks thread thought I'd start a new one..... Nice one on finding these mate, for any of you who have not used 4" mines they really are the holy grail of consumer pyro, certainly the most powerful items you can buy, while they may seem costly for the duration they really will knock the socks off of your audience! Get them while you can (I'd go for the colour to reports) because the likelihood is it will be the last lot you see on the UK consumer market. The sandling mines were the ones I used to buy after the minster ones disappeared and they are brilliant, being the size of a 4" mortar tube they look impressive in your set-up too! Come on Mark..... Video's....!!!
