I think its sad that Motel 6 and the PBA use a $150,000 prize fund in this way.  I'd much rather see an end of the year tournament to try and win this money.

I think they should make a final tournament with the Top 16 bowlers in points.  This will give bowlers an incentive to bowl all events and put a larger emphasis on points.  

Have the top 16 bowlers bowl 25 games of qualifying (5 on each pattern).  Cut to the top 4 for television.  All non TV bowlers receive 5k.  

For television, you choose the most fair pattern for all styles (probably chameleon).  You bowl round robin matches with the 4 bowlers and then the top 2 bowlers bowl 1 final game for the title.  You have two pairs for television so two matches can be going at one time.  

$50k 1st
$20k 2nd
10k 3rd 4th
5k 5th-16th

This was you have a little bonus for top ranked players.

I guess my only problem with the Motel 6 Roll to Riches is that its such a crapshoot to win it, and its for the PBA's largest 1st place prize.  I'd consider the trick shots like the all star game.  You don't win $150k for winning an all star game.

But I guess it's Motel 6's money, so they can do what they want with it.
