Steve,
Since I'm a Truckee resident, which makes us practically ex-neighbors, I'll be the first to respond. I have a 90cm carbon fiber Venom, and am very pleased with it. First off, the new trigger mechanism is solid steel, and massively strong, yet very smooth. This trigger is set into a very dense, very ergonomic handle, which I find very comfortable. I find that I can shoot this gun more accurately than any other I've owned or shot, and I beleive this is largely due to the positioning of the handle, the very low profile, flat top of the mechanism, and the very short, crisp trigger pull. The handle design, combined with the open muzzle, allows me to sight directly down the unobstructed shaft. I also really like the balance of power that the two bands provides. As far as accuracy, (at least for me), this gun hits exactly where I aim it, with no compensating for anything.
As for the "safety assist" lever on the handle, well, it's a love hate thing for me. First, I hate the fact that the safety has to be depressed before the shaft can be locked in place, although I've gotten used to it and it's not so bad now. I love the fact that the safety adds just a bit of added security, especially with the short trigger pull.
Now, as for the infamous Aimrite guarantee. I won't go into details, (as not to embarrass myself), but I about drove Rick and Angela to their limits with my bumbling, and they were outstanding.
As for the Riffe euro, I haven't shot one, but I've fondled a few and they are outstanding guns as well. I'm a big fan of Riffe guns and own a midhandle. (Which I'd probably trade for the Riffe euro if given a chance.)
Overall, I'd say you can't go wrong with either gun, and the only way to choose is to get yer hands on both and see which one you like the best.
Ron.
