Double on Hattonswood Broc or Millshadow Aster?

[Swespring]

I have a bitch with Millshadow Aster 3 steps back in the pedigree. I'm thinking of mating her with a dog that has Hattonswood Broc 3 steps back (Aster 4 steps back).
Anyone see a risk in this?
There are rumors about health issues when double on those dogs. Any truth in this?
Anyone familiar with this or have doubled on those dogs. Result?
The inbreeding rate would be 1,6% so that is no issue.

Anything is a risk and a gamble, I'd be researching the dog though you are doubling or trippling up on.
Sometimes there are reasons why you should avoid them and only your researching can determine if that is OK for you.
Also depends on who you are breeding for yourself or where you see the off spring going on to and also think where future matings will take you.

Thanks!
That is what I am trying to do. I have heard some rumors about these lines but I also like the lines when it comes to mentality and hunting ability.
So just trying to get some facts to be able to consider the rumors to be true or not.
Would be appreciated if someone with knowledge and experience with these lines could share this.
Also, it is hard when there is no health testing done on siblings and offsprings.

I've got a dog inbred 4x4 to Broc, an additional line to Merlinsbrook Evita also.

Dawnrazor can you tells us why doubling up on Broc or Aster is not for you?

Toy's come out of prams too easily sometimes on here so I'll just say neither dog was my cup of tea!
