@Infinity: Honestly, you are spending a lot of money, time, and effort on this. Don't let your decision be influenced on what other people think about you or trying to hide it from other people. In the end you want this to be something you did for yourself and you will eventually be proud of. Don't listen to people on these forums who have never done it and don't listen to people who do photoshops in their underwear and critique each others proportions. I have never met anyone who actually went through this and then fixated on their post LL proportions other than some very dysmorphic people who had done dozens of cosmetic surgeries besides LL. Be honest with your doctor and tell them you want to try for the maximum, but will see how you feel along the way and make your decision in accordance with them based on your health. Trust me, you won't know how you truly feel until you are actually post-op and in the lengthening phase. Lastly, consider this, this may sound counterintuitive (it was to me at first), but people will be much more understanding if you went through all this and it made a difference they can really notice rather then going through all this for such a small amount that nobody notices.
In terms of my height gain, I barely remember what it was like being 5"6. I have been 5"8 for more than half my adult life at this point (longer than I was ever 5"6). I feel like I have been this height my whole life and this is my natural height. It takes a little while to accept your new body at first (which is why people shouldn't make impulsive decisions and go for things like AL months after they finish lengthening their legs), but honestly now my longish strong femurs are my favorite part of my entire body now. My whole body image has improved in general.
