This sounds a lot like the 2nd Best Fund that I analyzed here:
http://www.tsptalk.com/mb/longer-te...ths-second-best-fund-method-2.html#post390873. That didn't work out very well either.
The thing about these types of systems is you are basically following a trend (~20 day SMA). When you decide to choose another fund instead, you break the connection to that trend. I guess you can preserve some of it by come up with a modification like:
If the best fund is an equities fund (C, S, or I) replace it with the 2nd best or worst equities fund. That's basically what I did with the C>S substitution I analyzed earlier. I do like using the C Fund as an indicator for the S Fund, but C really doesn't show up as often as the other Funds in this system.
If we look at the LMWF so far this year we have these results:

It looks to me like you are fighting the trend in this strong bull market and, so far a least, your not winning.
