Welcome. For 3/4" EL blades that Tim sells, they are not overly heavy and you don't run in to flexing issues untill you start getting in to lengths over 35 to 36 inches. The 40 inch blade has been a popular size for a while but it does flop around a bit if you dual with it.

I have dualed with both the EL and LED blades in thick and thin wall and I havn't really felt that they were hard to dual with.
