Yeah to be honest the reason I'm aiming for Welterweight is exactly that, I'd rather play the skill side of it than move to the heavier classes where strength and power play a larger role. It's not that I'm afraid of getting hit hard, I just think I can do better with my speed and long reach in the lower weight class.
I think I could easily go up to 74Kgs, and probably increase my strength a lot to go with it, I'm already putting enough work in, it would just be a case of eating more of the same.
Edit: didn't see a bunch of replies. Dropping weight wouldn't do any favors to my punching ability no, dropping the weight will be a balancing act between getting down on the scales and keeping as much of my speed, power and stamina as possible, I've no idea how well it will go as I've not tried anything like this before.
