As with most things there must be a starting format that you either stick with or evaluate & move forward from, the 2,500 staring stack & 10mins blind does not allow for creative play & does suit the more aggressive loose player, where as a deeper stack & longer blinds would suit the more tight conservative player.
After reading the comments posted it looks like we need to find a more happy medium, I would like to suggest just increasing the blinds to 15mins with a starting stack of 3,000 chips & starting at 7pm for starters
