Hey Tim, First to answer your question. I’d say the height of shins matters and you’ll want them fairly equal, but I’d also in a sense treat them separate. The big thing I mean here is don’t necessarily measure one and then measure the other off it. Definitely size them up to your proportions. Some people surprisingly don’t have the same length of both legs. That being said as you size things remember for shins, trim from the bottom up and not top down (when making them shorter) and thighs trim from top down not bottom up. Second thing, you may need to do some shimming of the armor You can see an extreme example of shimming thighs here https://www.whitearmor.net/forum/topic/47405-thigh-super-shimming-opinions/ It seems a little daunting and takes some work, but it’s not too bad actually and a great process for learning how to work with ABS paste which is also how you can fix cracks later.
