I didn't realise how complex they were before I started looking at them. I am just about ready to purchase now and have made my mind up on the Slamm Fury as being a good buy for my almost 10 year old, quality wise. Would anyone in the know out there, agree? The one thing I am still hesitating over is the fact that MGP seem to be the brand of choice. Am I right in thinking to get an MGP that meets the spec of the Fury I would need to up my budget to circa £150?? This is a new interest for my son and I don't think I want to spend that much at this stage until I see how he gets on with it. Also can someone explain what stunt pegs are used for and is there a way to lock them up in the school playground?
