Avalanche Green/Black Pearl uses PK18 and is stronger and earlier than the PG.
The Slingshot is weaker than the PG due to the core having less flare.
I have a Slingshot and an Avalanche Urethane drilled identically, pin over ring, CG stacked below. Both are control balls with an even arc, on the lightest oil than you can still use a resin ball. For me and my release, they handle the same amount of oil, with a very similar reaction. Only when the backends are long and dry does the Slingshot give the slightest hint of having more than an arc. Even then the Avalanche Urethane continues its urethane ways - arcing forever. Both still hit on the dry.
