I used to have a Selmer 4 valved picc with bottom sprung valves - worst valves that I have ever owned.
Most of the bottom sprung valves that I am aware of, have shorter piston surface than comparable top sprung models and this would be inferior in terms of being "tight" and in terms of leverage and wear. Remember, our fingers do not push the valves down straight and this skew causes valves to wear unevenly and sometimes bind.

If Brett Getzen is around, he can probably give us an objective manufacturers opinion!
Old Lou shares my feelings about plastic guides. I have never had a trumpet with "audible" metal guides and they are much more durable
