Upgrading Sigs to get Springer Sig

[atrain2015]

I have been trying to get the Springer Sig and Springer BP.  I offer 9 cards (plus more if possible) for either one but keep getting rejected.   The only sig I have is the Daniel Murphy sig.  I would like to try trade it plus more inserts for a better sig with the ultimate goal of getting the Springer sig and BP.  

Handle on Bunt is also ATrain2015.  Have Maul Bounty and FC, and Fisto FC on Star Wars if that helps as well. Thanks!

I am also open to trading my sig for Bowman Platinums I don't have. I can't help but chase sets and since I am having no luck upgrading sigs or acquiring the Springer cards I want, I figure I can change direction.
