Structure implications?

[StableHand]

What are your tact./strat. suggestions and considerations for this structure:

* buy-in $14,000

* 72 players start, 6x12tables

* winners of round 1 tables get buy-in back and move to semi-final 2tables x 6players

* 3 remaining from each semifinal table qualify for final. Chip-count is taken, and carried on to final, when 4th player is eliminated at each table. Semifinal is played out, and winner gets another buy-in back.

* starting chips, round 1 and semifinal = T100K

* 30 min. rounds, blinds
1st Level $1,000 / $2,000
2nd Level $2,000 / $4,000
3rd Level $3,000 / $6,000
4th Level $5,000 / $10,000
5th Level $7,000 / $15,000
6th Level $10,000 / $20,000
7th Level $15,000 / $30,000

* prizemoney
winner 40%
runnerup 15%
3rd 10%
4th 8%
5th 5%
6th 2.4%

More or less like the British Open, but more money, and not spread over two months. It's my first big buy-in tourney, and first at this kinda structure, so I'd appreciate any and all input. Obviously winning round 1 is an absolute must, and it's presumably the hardest and most luck-dependent part of the event.

This seems incredibly crapshoot-ish. Those blind levels are ridiculous.
