Single ply denim is a waste of time. I have blown too many to waste time with it. Inzer currently will not sell single ply denim with radical cut, because they blow too easy.
Double denim is better than single because it will not blow as easy. A tight single denim is just strong as a tight double, except the double is less prone to blow. Denim is all about fit.
The idea with velcro is that it allows you to get in the shirt. The top portion of the of the shirt closed.
If you want to go with denim, you can. I can guarantee you will have to go bigger than your actual measurements to get anything within your capability to touch.
For a beginner, the Fury would be a no brainer. Less money to invest...easier to fit...more flexibility in how its sized, etc. The choice is ultimately yours.
