whilst looking for places in Oldham, we have trained on a few floor types...

laminated tiles over concrete
rubber matting (saftey floor) over concrete
corregated wood (supposed to be a dance studio.. but had a leak and the floor turned into waves of warped wood)
squash court - just plain sprung wood
badminton court - sprung wood again

if the floor is concrete I feel it in my knees for a few days after.

try for wood
