700r4 lockup converter questions

I was hoping someone can help. After talking to converter manufacturers I'm more confused.
I'm having a 700r4 built for my combo. 327 10.5-1 comp 268 cam twin turbo blow thru and 12 psi. I guess it makes about 500hp.
I'm having trouble deciding on what lockup converter to buy. Some companies offer one with a stock width lockup disc(about half an inch) and say it's fine just don't go into boost on the lockup. Precision offers a converter with a multi disc clutch. I spoke with a guy at art carr and he is trying to sell me on their version of the hi performance one where the lock up clutch is 3.5 inches wide.
I should mention the trans will be setup so that it will not go into 4th under full throttle and it will not lockup in any other gear than 4th.
The extra large clutch adds $300 to the price, do I really need it? All input is appreciated.

If you're not doing any WOT shifts with the TCC locked. Don't worry with larger or more discs. You wont need them if you're only using Lockup for cruising.
