Please, please, keep it to a FEW walkups (or downs). Doing that stereotyped walkup/down constantly, just becomes you yelling "CHORD CHANGE NOW!!!" to a bunch of people who already KNOW when the chords change. Plus, a very large number of guitarists, since they practice alone for hours on end, have already baked a zillion walkups/downs into their bass notes and it's guaranteed that what you do will conflict with what they do; and since the guitarist who can change the way he plays something once it's learned is vanishingly rare, you're not going to get them to abandon their attempts at being both bass-player and guitarist....Add a few walkups here and there ....
There are times I play for three hours without doing that stereotyped walk up to the 1 chord, and I think it sounds better for it.
