Interesting cross , I believe barcia bale bitches and Aston dee bee and the surf queen line could potentially have interesting crosses in the future with Oriental Angel coming into the action

Doing everything right at present the beast with good signs of honest and aggressive chase from a lot of reports

For me I dont like 2 x 3 of barcia , due to barcias most common traits alone , eg bit silly and also most importantly, injury prone

Id prefer cross his litter mate sister thru another sire also offering different passing genetic traits in opposite sex crossing

And you get a nice outcross which wouldnt hurt your broods full aust breeding.
Can help with increasing soundness

Good luck , there is no wrong , just ones preference and their own knowledge on what their own brood needs or would benefit from more

Not fussed on either sires that have been suggested to be honest. She is a handy bitch, FB might upgrade her. Good luck with who ever you choose.

No need for a outcross sireline, already plenty outcross on damline
