3 balls. Urethane and two reactives

Usually 3.
2 reactives and one spare.
But on Monday's match I'll be bringing 4.
The Scandal, the Grudge, the Freakshow and the spare.
I wasn't planing on using the Grudge at the alley the match is at, because the machines there often keep the balls down there, and the machines don't stop when it happens like it does on the home turf alley.
So balls might come back with marks on them.
But I did so well with the Grudge on Wednesday's practice that I want to bring it.
The Freakshow is for when the lane becomes very dry there, which is highly likely to happen there since they put on so little oil there. House shot pretty much, but the volume is so small, and it's hot in there.
Bringing the Scandal because there's already a few marks on it, so if the lanes keep our balls down there, I'll stick with the Scandal.

For matches on home turf, I'm bringing 3 balls.
Grudge, Scandal and spare.

One medium/heavy solid (Black Eagle), one medium hybrid (GB2MVP), one medium/light pearl (Track Heat), +spare ball.
Works on most THS.

That's what i have done, two ball tote and I carry my spare ball with me.

Four.  Heavy, medium, medium to light and plastic.

Usually only use one ball and plastic, but when you have to go to something different having two to choose from has been very helpful.

I have a personal rule to not switch balls unless I've tried everything else first.

I've decided that I'm taking this one step further this year - I'm going to see if I can bowl the season with just one ball (and plastic for spares).  So far, so good after 9 games - the average is already up 15 pins albeit in a small sample size. 

Those league nights of using 4 balls in desperation, I'm over it....


Obviously bowling in tournaments and UBA/Bowling Federation matches in other houses, that's a different story - the full arsenal is coming out (4 balls and plastic)...

6 to my Challenge league, although I rarely bring my tournament arsenal stuff.  If I normally work with 6 options in tournaments, I believe in working with 6 options in league.  This also eliminates the excuse of "should have brought x ball tonight" that I hear from so many league bowlers.
