 I know C that a given Europa will weigh more with the trigear C but all Europas differ greatly in overall weight C depending on equipment and options C the original Classics being the lightest.

 The combination spring / bungee  approach sounds like a great solution.  Can't agree about the weight though.  Our group converted out mono to a trike C adding 23 pounds / 10kg.  A Hoffmann C/S prop added another 5 kg ( over a warp drive).

The springs didn't work for me. My bungee had been mounted for about 7 years (never gave any trouble) it seemed an excellent idea to switch to the springs.

It really dpends which fields you are operating from. I am based at a fairly bumpy grass field C and the springs turn the aircraft into a bucking bronco. Especially on landing C unless you push the stick forward C

the nose can oscillate to the point where control could be lost by an inexperienced pilot.

A bungee is far better for absorbing shock and much more forgiving.

So I recently changed back C but had a problem with getting the bungee as tight as I had before C and I now have what to me is the ideal solution: a spring on one side and a bungee on the other side C plus the safety cable. I should mention one incident with the new bungee C where the safety cable cut through two strands of the bungee C with the safety cable sving me from a prop strike. So now I have all the safety plus the comfort.

If you are not operating on rough terrain C then you shouldn't have to worry with the springs.

 

Regarding mono versus trigear C someone mentioned the better cruise performance of the mono. Perhaps there is a small advantage but note that it was a trigear that has flown around the world a couple of times C with very economical fuel consumption and a basic 912. It also made more 'local' flights from CA to Alaska and the Bahamas.

The weight advantage is also theoretical. I noticed that some of the more recent monos came in with a higher weight than my tri.

 kind of a corollary to the question; assuming you then have a tri-gear 

 (as we do; G-ROOV) what is the opinion of people when considering the 

 bungee nosewheel system compared to the spring system? (we have a 

 bungee but are thinking of changing).
