I've tried most of the blades out there and I just can't make up my mind... I like the Astra SP's...but also like the Gillette Silver Blues.....so I guess I'm going to have a little poll here..... out of those two which should I bulk order? I don't want to bulk order both just for cost effective savings...Give me your opinion on the two! Also I really liked the Gillette 7 O'clock blacks... opinion start NOW!
