Rebuy/add-on Strategy for WPT Sat.

[Wheatsauce]

Thinking of entering a sat. for the Reno WPT event this weekend. Here is the format:

-100+20 buy-in
-start with $200 in chips
-20 minute levels
-Players may rebuy any time they have 200 or less for the first 3 levels
-Players may make a single or double add-on at the end of level 3 regardless of chip count...add-ons cost 100...players recieve 200 in chips for each add-on.

Blinds start at 5-10...by level 5 they are 50-1000...by level 10 they are 500-1000.

What do you guys feel the best strategy would be in regard to re-buys and add-ons. With such a small amount of starting chips, especially considering the blind structure (by level 7 the bb is = to the buy in), is it worth getting both the add-ons?

Thanks
