Was any more work done to Punga after the off winter season? Rode it in October and found it to be very rough, something I didn't notice when it had mats, and really felt the (sorry don't know technical term) part where two separate pieces of the slide come together.... it hurt my back so much coming down the slide, had to sit up a little...is there any way to buff those parts out? Did anyone else experience this??? The experience was so bad I'm nervous to go down now any slide that doesn't have a tube/raft now at VB
