You lengthened 9 cm on your femurs which is still acceptable limit and depending on your tibia length it might not look too bad when nked. The guy above is asking for 25 cm total LL from 4 surgeries which will definitely look comical and I hope you agree with that.
Getting more matches at 180 cm versus at 171 cm is indeed logical result and it was worth it in your case to get to that height. I start at a very bad height of 165 cm, thus, in order to get rid of a height failo I need to lengthen at least 13 cm to stand at a strong 178 cm, which is doable with 2 LL if one pushes really hard.
I just measured my legs from ground to the base of the penis and it's 79 cm long. Since at night my sternum height is 136 cm, it means that my torso is 57 cm from the base of the penis to sternum. This legs is ideal for someone who is 157 cm tall. 57 x 1.618 = 92.3 cm so I need about 13.3 cm more leg length to have an ideal leg-to-torso ratio. My arms will look a bit short, but it won't look freakish level.
I am more concerned about my short leg-to-torso ratio rather than my short height to be honest. Yeah, below 173 cm is brutal but having short legs with huge torso at 165 cm is more brutal as it makes you look even shorter than you are. And, since my torso is not only long but also very wide, it makes me look squarish with this short legs and disproportion is very apparent between lower and upper body segments.
13-15 cm of double LL will make me look much better than I look now. You mention that some girls said to you that your legs are longish in a good way but I have the opposite experience: one girl recently explicitly told me that I have short legs. She mentioned it due to my short stride when walking. That's why I need full 8 cm femur lengthening as my stride is really short due to short and stumpy femurs. 5 cm is enough for tibia since I don't want to suffer from ballerina foot long-term.
If you've got short legs relative to your overall height then you don't need to stress over this - just go for the max amount you can, especially starting at 165cm.
I had about the 'normal' legs for my height (i.e. they were pretty close to 50% of my height pre-LL), so I have long legs now for sure relative to my torso. It's noticable, especially if you were looking for it, but the good thing is most people aren't 'looking for it', and even if they were some girls who cared about proportions there's certainly a lot more that care that you're 171cm.
It's really just a matter of what you can afford to prioritise. At 171 I could get away with one LL, but really needed to shoot for the maximum amount to get into that 'safe' height zone. 5cm would probably have looked better proportions-wise, but 0cm would have looked even better for proportions by that logic. If I was 178cm already and for some reason decided to do the surgery, I'd have just gone for 7cm absolute maximum because the tradeoffs wouldn't be worth it beyond that.
Being realistic, at 165cm, you'd going to have to shoot for maximum height gain, as that's going to be the best for your overall life enjoyment. Proportion discussions are really only for those who are already tall - if you're 16x or god forbid 15x, the most +EV move is just to max the height at the detriment of everything else so long as basic functionality isn't impaired (but if you can't play amateur sports again or do heavy squats, that's gonna be a price you'll have to pay, by functionality I mainly mean walking and that's it).
25cm is too much as that'll almost certainly cause functionality problems. They won't even do that in Turkey though so it's a moot discussion. If someone wanted to get say, 16cm (let's say 9cm femur and 7cm tibia, which is about the max you can realistically get aside from some very extreme outliers), that'd still be worth it even with really bad proportions
if they were low 160s or below in height.
Basically, I think proportion discussions can start once you reach about 5ft 10/178cm. Before that, every cm is too important no matter what it does to your wingspan ratios or anything else.
