I have a friend that's going to nationals, and he'd like to know which ball has the smoother reaction.  I'm inclined to say the Messenger, although I've never thrown either of them.  Any help would be appreciated!

The only difference between youth and adult leagues are that the big boys are allowed to whine.  They're more entertaining anyway.

Bowling? Of course it's a sport.

Ok, thanks.  He's wanting to use them on toast though, and I don't think that's possible.  Of the two, the Eraser hooks hardly at all, it seems to have died somewhat.  It'll hardly hook two boards at a house I can hook the lane with a Viper at.  But I just don't think either of them will do what he's wanting.

If he is looking for something that is more controllable...but for toast I would say to look at the Sonic-X or possibly a Tour Power with the correct drilling and surface prep.  I've got a N.I.B. 16lb Tour Power with a 5.5" pin that will get him down the lane REALLY well.

oh...thanks for the clarification.

I would say that a polished messenger would be less flippy.  However, neither are really good for a dry condition.  For screaming backends he might to hit one of them with a scotch brite pad...since the slightly non-polished surface will cut down any over reaction to the friction.
