Question about Jab, Cross, Left Head Hook combination

[BoxingDude66]

I've been trying to come up with an easy flurry combination that is devastating if used correctly. The combination I was thinking of was the classic 1-2-3 Jab Cross Left Head Hook combination. It is a move in combination, moving in with the Jab, a short compact Cross, and a Left Hook that hopefully either hits the chin or the temple, causing a knockout.

I liked the combination, but I feel it was too short and I didn't want to end on a Left Hook, since I'm better suited to the Cross. So I made it something like 1-2-3-2-3-2 (Jab, Cross Left Hook, Cross, Left Hook, Cross), a flast flurry, combining the stereotypical Outside Fighter's 1-2 with the Inside Fighter's more lethal 2-3-2 or 3-2-3 combinations.

However, I'm wanting to know if I should shorten the first Cross punch, like a 1-2-3 combination, where you move in with a Jab, short Cross, and strong Left Head Hook. I think it if you lengethen out the Cross in the 1-2-3 combination, it will throw off your balance when you let loose the Cross, Left Head Hook, Cross follow through. What do you guys think?
