Middle Weight

[shirase]

Im new to thai boxing and I realize that at the moment I am in no condition to compete, but in the future when I become more skilled im interested in competing. At the moment im also doing lots of weight lifting to generally get bigger and stronger. I was wondering however, at the moment i am 16, 5'6-7ish and weighing in at 148.5 lb.s ish and if I competed in the shape im in now I would probably fight at 145 lbs which is i believe welterweight(at least in boxing it is). I was thinking that if one were significantly shorter than their opponent in thai boxing it could be a problem in the clinch because your head is closer to their knees and your head is farther from your knees. Its not unheard of for middleweights to be over 6'0 so that could be bad. So do you think that if I moved up to middleweight(160 lb.s) that I would be at a disadvantage? Please give examples and your own experiences in the ring, because ive been thinking about this.
Note: this assumes I will stay the same height, im only 16 so I suppose it could be possible but I havent grown in like 3 monthes so im not really holding my breath over it(besides my dad is 5'7-8ish and my mom is 4'11!)

My first reaction would be to say that 160 is too big for you.....but it really depends on the fighter. If 160 is where you feel the most comfortable then go for it! A short guy can do allot of damage to a taller guy's legs in the clinch! Just keep training hard and see where your body ends up.....
I'm 5' 10" and my first fight was at 158, but 3 years later I'm fighting at 140. I'm in a lot better shape now, and that's just the weight I ended up at. Hope this kinda answers your question

Ive been thinking that I will go up to 155 lbs for walking weight and that since it will be a long time before I compete i will be able to go up or down depeding on how I feel. My cardio is pretty bad now because I havent been doing much of it in the last year because ive been bulking and I had a few injuries. Im actually leaning towards welterweight (145 lb.) right now because its probably more natural for my body and most welterweights are close to my height. Thanks for the reply!
