Variation in jump height has been played around with before and the bigger hump used to raise up (a 2m section is another option), it all depends on the track design and location of a higher jump cos as is evident at any race meet and was highlight at the AGM - 40% of the members are Juniors and there safety along with any members safety is key.
One of the recent track designs (if not the one before the current one) had a higher jump, not sure if you raced that one Team Mad Rat (wish people would put there names on somewhere if there not obvious so you know who your discussing a topic with
).
Anyway what I'm trying to say is it's possible.
We could use the mats as long as they were covered and we ensured they didn't get damaged.
Think the best thing I can suggest is put some track designs together with optional features in and pass them onto me and we'll see if we can make them work.
Please note though additional features require additional work laying the track and if your only suggesting and not taking an active involvement in the club (i.e. helping lay and take up track/carpet/etc. at the beginning and end of the night, then don't expect others to push the boat out for you).
We try to encourage people to get involved in the club and not just turn up expecting a perfect track to be laid for them, so please do your bit and get involved.
P.S. The agreement at the AGM with regards frequency of track design changes was a the beginning and at the mid point of the Series, we now have two Series in the year a 'Spring/Summer' and a 'Autumn/Winter' the agreement was we would run the current track until the mid point of the 'S/S' series and then introduce a new track after the usual vote, so get your designs in then I can work them up before we vote.
