Cobra Fly z XL Hybrids

[ThumbtackR9]

Just bought some like new from Callaway Preowned clubs two Cobra hybrids.   I bought a 4 and a 5 hybrid.  Both have the fly z shaft in light flex.  Both look like they were hardly used.  One has a winn dry tac grip in 1/16" oversize and one ( the 4) has some kind on jumbo type grip.  It is almost the same size from top to bottom.  I use a standard grip my self which is about right from how you tell if you have the right grip.  Anyway I took both clubs out to my hitting net in my yard and took a couple of good balls to hit.  I also put the stickers on the face so I could tell where I was hitting the ball .  I started  off the small matt I have.  I used the 5 first.  The club feels good when swinging it.  It almost has no sound when you hit the ball which I don't care for.  I tried the 4 with the jumbo grip and I could never hit the ball in the center of the face.  I tried to hit on the matt and then went to the grass.  Didn't really seem to make any  difference.  I could do fairly well with the 5.  I just wonder if the grip could make that kind of difference.  I always hit the ball low on the face.  I really figured the club would have a good tink sound but it doesn't.  I went back a read a couple of reviews and they said it doesn't have much sound.  I took the stickers off the face and just barley punched the ball with both clubs and the sound just isn't there.  I have a callaway 6 and a callaway 3 hybrid and they sound completely different.  You can really tell when you hit  the sweetspot with the callaways but I don't know how its going to be with the Cobras.  Does anyone use these clubs and what do they think about them?

I had bought some Cobra Fly Z irons 6 through pw so I got these hybrids to go with them.  I am going to regrip all of them with standard Winn Dry Tac grips.
