if you want to bash id go with 18/46 (pinion and spur) but for racing where you want it to rip out of the corners id go 16/48 which is what i run now.
 
As Sper says 18/46 is a good all round mix and I personally wouldnt go higher than this (eg 20/44). 16/48 will give you a bit less top end but more bottom end zip. Count how many teeth are on each of your gears now to give you an idea of where you are now and which to go for. You may need a new gear carrier depending on what you are running. The ratios should add up to 64 in total for correct meshing.
 
PG racing . com do the white Delrin spur gear which are as bullet proof as you can get. I had mine on for 2004 & 2005 (2 seasons) and apparently it still on the car after I sold it.
 
these gears are good ive got 2 mates that run them on there marders but as said above check the flats on the clutch bell and layshaft,,as on some there different and the flats arent on opposite sides,,,i know they don't fit the tuning bell and comp layshaft as ive got them on mine and they don't fit that
 
was running 18/46 on marder ,now 22/42 and the top end is great,for big fields, i don't seem to loose as much bottom end as i thought.today raced my mates marder which is also 29cc with same ehxaust and they were always equal in straght line speed , they both left the line together and got to mid speed kneck and kneck but as soon as my engine hit top revs and jetpro came alive it left it in dust! you got to remember that when u run 18/46 you get wheelspin, thats why i kept up with him on initial accelertion,but still got a bit of wheelspin myself but more controllable.It would be a waste of time in small spaces as it takes abit longer to hit top revs,try it,youll be surprised of how little bottom end you lose if any due to better traction.
