Ladies and Gentlemen:

On behalf of this firm's  client,  Citigroup  Managed  Futures  LLC, the general
partner of the Partnership (the "General Partner"), we respectfully submit below
the General  Partner's  responses to the comments of the staff (the  "Staff") of
the  Securities and Exchange  Commission  (the  "Commission")  in a letter dated
September 27, 2007 to Jennifer  Magro,  Chief  Financial  Officer of the General
Partner.  For your  convenience,  the Staff's comments are indicated in italics,
followed by the General Partner's response.

Notes to the Financial Statements
- ---------------------------------

7.  Financial Instrument Risks, page F-18
- -----------------------------------------

1.   We note that the Partnership  and the master funds may make  investments in
     assets that are not traded on an exchange.  Explain to us the Partnership's
     and the  master  funds'  policy  for  determining  the fair  value of these
     assets.  Additionally,  to the extent the  Partnership or master funds have
     any such  investments as of period end; tell us how you determined  that it
     would not be  necessary  to disclose the  Partnership's  and master  funds'
     methodology for calculating the fair value in the policy footnote.

The Partnership does not engage in any direct trading.  All trading is conducted
through  the Master  Funds.  The  majority  of the Master  Funds'  trading is in
exchange  traded  futures  contracts  for  which  daily  settlement  prices  are
available.  Currently, all off-exchange contracts traded by the Master Funds are
traded in commodity  interests for which there is generally a liquid  underlying
market  and are  valued  by  reference  to the  settlement  price  of a  similar
exchange-traded  product.  The Master  Funds'  off-exchange  contracts  to date,
therefore,  have  been  valued  based  on  the  settlement  price  of a  similar
exchange-traded product.

In the event that a Master Fund  trades an  off-exchange  contract  for which no
similar  exchange  traded  product  exists,  the General  Partner will value the
off-exchange  contract using one or more alternative valuation methods which may
include,  but are not necessarily  limited to,  reliance on assessments  made by
internal product control teams affiliated with the General Partner.  The General
Partner will include a description of any such  alternative  valuation method in
the Partnership's policy footnote in such event.

The  Partnership's  current  disclosure  states,  in pertinent part,  that: "The
majority of the Partnership's positions will be in . . . exchange-traded futures
contracts.  Exchange-traded futures contracts will be valued daily at settlement
prices  published  by the  exchanges.  . . . Swap  contracts  held by AAA Master
generally will be valued by reference to published settlement prices or dealers'
quotes in related markets or other measures of fair value deemed  appropriate by
the General Partner. The General Partner expects that under normal circumstances
substantially  all of the  Partnership's  assets  will be  valued  by  objective
measures  and  without  difficulty."  The  General  Partner  believes  that this
disclosure is currently accurate.

                                     * * * *

Should you have any questions, please do not hesitate to contact the undersigned
at (212) 728-8727.

Very truly yours,
