The CiS system (Cash is Stock) will take care of some of the money management issues automatically. The buying will continue to deeper drawdown levels, these days a transaction cost 50 cents, so using Lichello's one percent rule, the minimum transaction size is 50 dollar/ponds/euros, so really deep drawdowns.
Another advantage is psychological: the buying is more confident, without the fear of crossing the no-cash line.
Also using 'growing' stocks for a 'cheap' price with nice earnings will help.

PS. Today installing my solar panels, which will return 15% per year. Payback 6-7 years. That is a nice investment.
