I presently have 50 thousand in my 401K it is in Vanguard Instituti0onal Index, this is the only index fund available to me. I am saving up to start a Roth. I could start one now but thought it would be best to want till I had the years max saved up to save on that much quaterly fees. So what I am looking for are suggestions on what Vanguard fund would be the best for balance for my 401K.

As a little mopre background I wil be retiring in 11 years with a small to medium size pension.

Thanks
