Ideas on a money mgmt strategy

[smh1@xxxxxxxxxxx]

Hello all...
   In the new year I'm planning to daytrade a basket of around 6 or 7 
different e-mini contracts (e-mini S&P, e-mini Nasdaq, etc.). My 
starting capital will be around US$30,000 and I'm just wondering 
what sort of money management/position sizing strategy would be 
optimal (and keep me out of "ruination").
   Should I allocate a similar dollar amount evenly to each of my 7 
instruments and treat each individually, or should I treat them all as 
one singular 'basket?. It's a toughie. Any input would be most 
appreciated!

Cheers
   Shawn
