Uncle Kumar Super 4D and Pow Wow 4D are very popular. You can use the set for a maximum of 3 draws/races only. Maximum you can spend every draw 3 draw is a small amount, so why write just some numbers that are normal? Why don't you write numbers that have been mathematically predicted by the Mathematics Wizard of 4D Number Uncle Kumar?
Why Uncle Kumar set a maximum on the 4D Number tips of 3 draws/races?: This is because patterns of winning will change every draw and it is not logical to hold on to a single pattern for long. As you move along, you can buy new sets as per your budget and keep playing. Never loose hope. Play within your budget and if you win it is SKY HIGH. If lost, just lost the betting money. The important thing is keep on playing. If you stop play, you are out of the game.
