i see a lot of people very hung up on weight #s but what you see in the mirror to me is way more important unless of course you are doing competitions.. to me looking at your last two pics you look the best on the very last pic. Even if you are up on weight you look better imho in that last pic.. you are lean enough and do resistance training that CBL is probably your best bet just don't go to crazy on back-loading nights(looking at your log it seems fine) and you may gain a little bit of weight from muscle gain but doesn't look like you are adding fat as your abs still look good and doesn't look from those pics like you are putting on fat. Females in general hold a lot more water weight which is my guess on the weight fluctuations
