/chotbar change 2
and
/chotbar change 1

those two macros will allow you to swap hotbars without turing them off.
so, instead of letting go (or turning off a hot bar if you use toggle/mixed) you can switch instantly.

think:
let go of l2/r2
l1+desired hotbar number
engage l2/r2

or

x (or whereever you drop your macro)

From a simplicity standpoint, the choice is obvious.
