You're comparing two different heads. The G1 is the standard single-ply head. They still make the regular Genera (and also Genera Dry with vents) which has the muffling ring.Mikkey":34xyzsr6 said:I really like the Genera (G1) coated before they changed the design of the head and took out the ring. Just for museum value, I held onto one of the old genera heads and compared it to the newer one. Not the same.
