Depends on your game, how you throw the ball, and the lane surface. Which E makes a difference also.
E on synthetics, I have used Eraser Particle, Super Power with good success, used a weak Recharge well once.
E on wood is another animal. In our region, we usually on use E on beat up wood, it is the most playable condition for nasty beat up houses. Resin works better here, usually shiny and not very flippy. I have an Eraser with the pin 1 inch from my PAP, pretty much only use this ball on E, works well though. Pins over the fingers with shiny resin/pearl resin works well later in the block as the heads get beaten up.
You don't need balls that create entry angle for you, the lane/breakpoint will do it for you. You need balls with a controlled break point. E can be wet/dry, using balls with a little surface to them usually fixes this problem.
Hope this helps/your mileage may vary......
