The main issue I have with carriers is that I think we are talking about a situation where you are caught off guard...this may mean you are scrambling units from your fleet or having to quickly build new ones and then dispatching them to a location several jumps away...
If you are building new units, the carriers will need time to build fighters...and constant jumping is only going to make matters worse since you'll have no AM for construction...
If you are sending ships you already have built, I'd prefer LFs...carriers are more important to fleets, I'd like to keep them at full AM, and they are slower than both scouts and LFs...
On the other hand, SC themselves move fast, so if you can get to the grav well quick enough the ogrovs can't even do tricks to avoid fighters...after all, fighters move faster than scouts...
