LVM LV raid5 - can it be extended?

hi everybody

I wonder - is it feasible and safe to extend LV raid5?
I'd be trying to add a few more disks which will become PVs in their entirety, then use whole PVs to extend LV.

Also if possible interesting would be to know if resyncing such an extended LV could be negated by re-creating LV anew if it's (resync) faster. In other words: lvextend raid5 + resync VS lv(re)create raid5 resync.

many thanks
