M-
We use the t-slots until we have chain cut and drill through and bolt once everything is in a final position. The bearing blocks we have are slotted and allow for minor adjustments if necessary. Our t-slots always wound up sliding in the 80:20 and wound up being more maintenance that it was worth without bolting through. After 4 years of this, my advice would be to go ahead with the t-slots and if they never slip, great - but leave yourself space to drill and bolt through just in case. It's a quick enough move with a hand drill and some 1/4-20 bolts.
