That's the good part of being 5'7" and training in the USA...you get used to facing always bigger people coz it is very hard to find someone smaller than you.

And as per Sankyo...if it is done properly you don't need strength. A good Sankyo is hard to break coz the position of arm and wrist make so that you can't apply strength to break it thus you don't need strength to hold someone in Sankyo...
