There's not much to say about the A4, other than good choice. It's an excellent marker that's ready to go from the box - after a battery charge of course!
Personally I like to give Angels two full battery charges before use, but that's because I worry too much.
Depending upon your mid's bottle size, the number of pots he carries and the average air fill you can expect to get at tournies, he might want to fit one of the volumizers that comes with the A4. He'll be reducing his gas efficiency, but he'll be a little lighter on the paint which might be of some use.
The trigger is very easy to adjust via the external adjustment wheels, so no more need to have a tech do it.
For paranoia's sake, you could check that the ram stroke & LPR pressure are correct and that the anti-double balls have been screwed down, but since it's new from the factory, there shouldn't be any real need for this.
That's it really.
And sorry for your mid's loss. I hope the thieving b*****d who took the Angel gets locked up in a cell with a guy named Bubba who wants to play 'pick up the soap'.
