Board construction is one of the toughest balancing acts. The loads and (more importantly) the expectations of durability are HIGH. Basically, consumers expect that the boards will be as durable as their twin-tips. However the materials used are more similar to what was in twins and wake-boards 5 years ago!
Surfboards are built of EPS or PU foam, wrapped in glass and hard foam. These materials are great, but will never yield the strength that is similar to the wood core twins.
The realities for surfboard feel are that there is a certain amount of flex that is needed to make a shape come alive. you can build a board to minimize breaking and denting, but the boards start feeling stiff and pingy. This is ok if you are using straps, but lets not talk about that....
Weight is a key factor as well. I have boards that are 6 lbs that are my absoute favorites, but guess what, they are dented. in 7 weather you have to be quick to get back to it or it blows away. I have other boards that are dent free, but they weigh 9 lbs. That is an ok weight for a skate, but they loose feel and are not that fun in the air.
The Chop Top and the the 2011 Skillit are both sandwich construction boards and should be pretty good for feel. The 2010 Skillit is build with a hand lam over EPS. It is truly a surf feel, flex, and weight. It will dent.
Personally, I build my boards with optimized deck reinforcements of Carbon, wood, and some sandwich. I am willing to let my boards wear out over time and don't mind some amount of denting. The boards flex properly and are light.
