Up front, with the sway bar connected, it probably won't bind enough to hurt flex significantly. It will in the rear though (rear flexes more than front with the sway bars on). Plus, if you're flexing it a lot, that binding puts more stress on the control arm brackets too and increases the risk for one failing.
If you want to tighten things up beyond the rubber bushings, I'd go for some arms with either flex joints at both ends or poly at one end and a flex joint at the other (joint at one end is enough to keep it from binding). It'll ride a bit better on one-sided bumps without the binding as well (but without the sloppy feeling of soft, squishy rubber bushings). Poly is perfect for the track bar bushings though (it doesn't move in a direction that'll bind the bushing).
