My friend has an almost-new Trespass that I borrowed to test out and compare it with what I thought were similar discs, based on the flight numbers. He had had one hard, rough hit with it, though, so part of the edge was pretty roughed up (I worked to smooth it out again). When I started throwing it, I thought perhaps that one hit had completely altered the flight characteristics of the disc already, but reading other reviews, it sounds like this disc tends to be much less stable for people than the numbers suggest, so maybe my experience wasn't a "beat in" factor after all. (Still, I think a better grade plastic would be recommendable for any distance drivers so they hold up better, longer.) That being said, once I saw how the disc was flying and threw it accordingly, it really got some great distance for me because it was easier to get S-curve throws than with my Destroyer, for instance. The speed might still be too much for beginners, but the understability I found would make it a quicker disc to advance to than other speed-12's. The Prime Burst plastic looks cool and feels good, and the Trespass' shape also feels good in the hand and releases easily and consistently; personal preference would be to have it in a better grade like Opto. So overall a great disc -- just be aware it might be understable rather than a DD version of the Destroyer, as the numbers would imply.

Definitely more under stable than flight numbers suggest. I have 3 and they've all become more flippy. That being said, for me (relatively new beginner-average player) this is my furthest flying disc. 
 

Solid Driver, Distance can Surprise you, Don't trust the flight numbers

For reference, I typically compare drivers with these flight numbers to a Destroyer, and this disc does not feel or fly like a Destroyer. To me, the grip and feel is comfortable, and the rim feels a bit smaller than a Destroyer. I don't totally see it as a bad thing, but it is definitely more understable than the flight numbers show. With the wind, on a still day, or down hill, this disc can be one of my furthest flyers. However, with much crosswind or a headwind, I will typically select something else as I have seen this guy turn hard and land a fairway over multiple times.
