How do you guys set up your bowling arsenal?

I have read a couple of articles on this.  The one that I thought was a good one is this.

2 sets of 3 balls.

SET 1: A heavy oil, med oil and light oil ball all with a power stacked layout.

SET 2: A heavy oil, med oil and light oil ball all with a label layout.

This gives the bowler a 6 ball arsenal plus 1 for a plastic spare ball.  This will cover a lot of conditions with only two different layouts.

What do you guys think about this set up?  I personally feel that this set up could loose one of the label heavy oil balls which brings the arsenal down to 5 balls plus the spare.

How do you guys go about setting up your arsenal?  Do you stick with only a couple layouts or do you lay all the balls different?

I like to make things simple and feel this is a great approach to building an arsenal.

That's a pretty cool approach.
I was just reading an old "ask Mo" article in BTM and he set up some pretty interesting arsenals based on initial ball speed
for high speed bowlers it was 4 high flare potential particle balls (2 drilled for high flare, 2 drilled for medium flare) then 1 strong reactive high flare potential ball drilled for high flare and 1 spare ball.
For Medium speed bowlers: 3 high flare potential particles (1 drilled for high flare and 2 drilled for medium flare); 1 strong reactive high flare potential drilled for medium flare and one weak reactive drilled for medium flare and a spare ball.
for slower bowlers: 2 High flare potential particles(1 drilled for high flare, 1 drilled for medium flare); 2 strong reactives high flare potential balls (1 drilled for high flare, 1 drilled for medium flare potential) 1 weak reactive drilled for medium flare and a spare ball.
He wasn't too specific about the drillings or coverstock prep, but it was still interesting to look at the different possibilities.
  But looking at what Mo's article said, it comes out pretty much like the article you drew from.
For me six balls is too many for me to manage.
For league I take two balls plus my spare ball.
I take two medium reactives, one solid drilled to arc(RS-X) and one pearl drilled to snap (Vibe).
For tournaments:
One heavier loaded dull particle drilled stacked leverage, which rolls real early for me, for Heavy Oil (Silver Streak Particle)
One light loaded particle drilled label, for mediums and an arcing reaction (Impulse Zone).
One pearl reactive for mediums and a snap reaction (Vibe)
One low differential weak reactive (Big Hit)
Especially for tournaments with 3 game qualifying rounds, this is enough for me to try and manage.  However I would like to add a good Particle Pearl to that line up before fall.
