Thanks for the advice guys, even though my post is half a year old
I've decided to take dubya's advice and basically go with what feels natural. Me and a mate of mine have basically been teaching ourselves how to wrestle on a mat in our local gym (as most should already know by now, wrestling is non existant in the UK).
I'm getting better and have a pretty excellent sprawl if I do say so myself. My friend is shorter than me and clearly has the advantage in going for double leg takedowns and such. But I feel like i'm better in the clinch. At least better with sweeps and trips and stuff. But he is stronger than me so he has no problem using his hips to throw me about.
BUt yeah, I like wrestling and wish it was taught in the UK because it's a powerful form of combat. I've been learning a bit of Judo as well just to get an idea of the differences and such. There seems to be a strong emphasis on technique with Judo, so learning it is pretty difficult for me, but my timing ain't half bad as well as my trips. It seems that I have an advantage with trips and sweeps whereas a shorter person is better at throws.
As for the striking..well, I have these very long arms so i'm practising on using length and stuff. I don't think I have KO power, though
My hands just don't feel heavy. They actually feel pretty light. My forearms aren't huge either, so I doubt that helps. I'm getting better at using my hips to transmit power. I just don't want to try it on my friend for obvious reasons.
