I appreciate I'm not a Torch member, or even from your area, and you don't know me...but the topic of triples made me curious as I build the tracks every week at out indoor club!
The best jumps/triples/features have a nicely curved up ramp to make the transition smooth to take off...then a good length (typically much longer!) down ramp to give you something to aim at to land on....something that is a good few times the length of the car for example. Landing on the flat is seriously hard work for the cars...even if they fly well, landing is still a bit of a risk! Blown shocks from long heavy landings and nose diving short into up ramps aren't a lot of fun!!!
Without a good landing area to aim for it turns into an obstacle rather than a racing feature...that only the very best drivers can hit lap after lap. A decent bit of a landing area gives you much more tolerance on your speed and control, which, if you have a variety of skill levels racing on it (like every club has!) makes it much more fun in my experience...even for the best guys!
If your still experimenting with jumps, take the time to play with jump lengths and down ramp and up ramp shapes...it'll make a huge difference to the fun levels! If you can when your building your jumps (presumably from wood to begin with?) make them variable/adaptable in some way to make changing them easier to begin with until you get it right.
The only other thing to play with is features that aren't jumps...but changes in level/gradient/camber. Offroad tracks, to me, should also have shape to them, in all directions!!!
The new track you've built looks great by the way (if a little flat so far, but you know that

), wish I was closer to it...keep up the awesome work guys!!!
