ibanez s series

Has anyone found any problems using dunlop straploks with the S series. The upper cutaway is so thin I'm actually kind of concerned the screw is going to loosen or rip right out of the wood. Has anyone else used this configuration with no problems? Any recommendations? I have it set up but...

Hey guys I'm looking for an S series with 24 frets. I was thinking egen18 but too expensive. What are your opinions? I play mostly metal n' rock through a peavey 5150 combo. Thanks!
