dude dont worry about hurting the plant... kick the crap outta them... FIM both plants... and dont worry even if you mess up on a FIM youll simply have a topped plant... so 2 new top branches instead of a possible 4+ with the fim... these plants are hardy and seeing as they are super healthy lookin, beat them up a little, they will love it in a couple weeks when they fully recover and have twice the growth tips as before from a simple FIM or 2... i honestly dont know why so many people are scared to top/fim/LST of any type... FIM away my friend. i just FIMMED my Sleetstack X Skunk in about 9 places, the top and like 8 lower branches, now just 2 days later they are all already starting to recover and with about 4 new growth tips per spot i FIMMED, the NL x NL i have got a single FIM on just the top and in a week or so the remainder of the branches. lets just put it this way, i started with my Sleetstack x Skunk having 15 "new growth tips" one on top and 14 lower branches, i FIMMED the top and 8 of the 14 lower branches, now just 2 days later i have at least 36 new growth tips, by simply FIMMING, the plants seem to love it and why not do what you can to get as much outta the plant as you can especially if its a good strain, why not?...
