Silicone Velcro chest plate?

[Beanbott]

This item sounds great, but I have questions.  What are the pros and cons of this compared to glue on forms?  And how does the Velcro plate compare to similar items from another manufacturer which are more apron/bib shaped?  Have there been issues with the larger sizes being too heavy and tearing the silicone around the forms which holds it all together?

Also, could you please post some comparison photos of the different sizes you sell?  Some front and side shots would be great.

Thanks!
