Heh, I wish I was a pro! I'm just a dude experimenting with botany, probably the same as most people here. I just read a lot!

Anyway, yes, I did top those plants, and topped my current crop too. The downside is, you have to give them time to recover from it, but I have learned patience. Also, from what I've read anyway, whether topping does anything beneficial is entirely strain-dependent. Some strains will never reach their full bud potential without topping, and some strains will just spread the bud mass they would have had with one gigantic top across the multiple tops, resulting in no extra bud mass. I can say with certainty that AK-48 and White Rhino react favorably to topping. It appears that Durban Poison x Skunk #1 and Blue Mystic also react favorably, but I won't be positive of that until they're done flowering. Either way, it won't do you any harm to top them (except for the recovery delay), but it might do a lot of good if you do...so I would top them.
