The tracks I have raced on so far this year haven't really had any large jump, as shown here
http://www.oople.com/forums/showthread.php?t=168224 , although I'm likely to require more pack at the next few venues we head off to.
I believe something like:
Front:
2 x 1.6mm
35wt
Black Spring
Rear
2 x 1.8mm
32.5wt
Red Spring
Is also proving pretty popular with the UK TLR team from looking on the Horizon UK facebook page.
