If you feel more comfortable tweaking it a bit, I see no reason not to, as long as you're doing it for the right reasons (e.g. making you feel better, not chasing better performance this year/month/week). Personally I run with 4x25 standard PPs in my primary accounts, but have more typical stocky-and-bondy portfolios in IRA accounts where I can't easily or cost-effectively implement a PP.
If you go with a PP in anything close to 4x25 you have a better portfolio than 95% of the US population.
Hell, if you go with 50% total stock market and 50% total bond market you probably have a better portfolio than 60% of the population.
