Better material, doesn't warp as easy. Harder to find, but alot nicer.8) If you do score a DP 95 make sure you hit it with a couple of coats of "sandable primer" first otherwise the emamel won't dry completly a will remain tacky.
I had that problem with my '95, which was the first helmet I owned. I've also heard the horror stories of people having left their vinyl noggis in a warm car, only to find it's gone soft and the original shape has changed.
My next helmet was a DP Deluxe. Forget about it! About $650 down the tubes. The visor was flush with the mandibles, rather than recessed, and it was puttyed on the sides so the wings of the Tvisor were too short.
For a time, there were some castings of modified DP Deluxes available. I even saw fiberglass recasts of the undersized DP '95.
My next helmet was a MS (movie sized). Very nice and good craftsmansship. Later, the bar was raised by Fettpride to make the MS2 (second version).
Then I got the MR (Master replicas) version. Best yet, except for the pinched visor that I'll need to modify.
Don't have a Mystery, but would like to, just to paint up another variation.
I like fiberglass, but as said before, for your size, the DP '95 might be the way to go. But I did fight the tackiness problem.
Good luck on your search!
