Springfield is a better borrow when using QJ+Vector+Sharkry. This is because her bird will ensure that QJ gets 6 supports and Sharkry gets 5 supports per turn. Using your own TLL here is a waste since this team will do a lot of damage (score formula is a root function). If you do put TLL into this team, then you will likely kill on turn 6 (so you must deliberately hold damage since an early kill is -182 points)
HK416 is the best borrow for G11+Peritya. This goes without saying.
Springfield is a better borrow when using TLL. Assuming you don't bomb your own TLL on the burn team, this is a forced play on your third team.
