6ft 1 is not a bad height for a teenager considering you're still growing. However, there are some 6 footers that weigh 130lbs... now that's considered tall for their weight.
I'm 6'1" and in the 165 weight class in the ams. I'd say most people I fight are at least 2 inches shorter than me, but it's not a huge difference. There are some huge mother ****ers in my weight class. For instance in the NY GG tourney 2 years ago the guy I fought was 6'3".
160lbs is quite strong weight for a young age. you wouldnt be too tall. no way. im 5'10 and weigh 175lbs but im 20, looking to lose about a stone.
