You will pay a bit more if you are specifically looking for Aardens, if you go for the £131 (6) or £190 (10) offers the will pick the distance birds for you but I'm sure there'll be a few Aarden bloodlines amongst them.
The modern day Aardens that they have look the part and are close to the new champions of this great strain, I'd say they would be worth a try. Like Walter I still have a lot of the old bloodlines in my loft and they're still turning out results
