TWM - hope your Aerial Assault works out.
I had a less expensive Do-All trap (a 3/4 cock seated trap) and it kind of fell apart on me. Upgraded to a Lincoln 3/4 trap and have had *great* luck. It is very reliable, throws everything from battues to rabbits to teal and rarely breaks a clay. Anyway - for anyone looking for a recommendation, take a look at Lincoln's traps.
