i would recommend putting 50% aside after the 5th level, then 3/4 aside after 9th-10th level and play with Free Money, obviously it would make you go back in lower levels but it would be a safer way of compounding your profits in case you lose the whole 100% and no balls of steel needed well maybe IRON balls ... LOL
knowing myself i would start at the 3rd level with the 50% reserve
