Lane #1 Chainsaw has the market cornered on weak resin right now. It's in a totally different category from everything else.
Most of the other stuff I would suggest is discontinued. The Blue/Green Centaur is the exception to that (I think it's still made). If you can find an AMF Heist Pearl, it would be a good choice. You can still find them on eBay but they were not released in wide circulation in the first place and your AMF dealer is unlikely to have them.
Beyond those, here are a few oldies you might still be able to find NIB somewhere: Ebonite Matrix Conquest, Track Threat (particle pearl), Banger Hole Finder Pearl, Dyno-Thane Cure Pearl.
