Question about Jab, Cross, Left Head Hook combination

[Leo]

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?

Uhm, yeah. Rather than think about this, you should test these combinations on a live, resisting sparring partner and see what works in practice.

It'll be fun, trust me.
