Thanks for the opinion of all of you. This is the first time I use an internet based forum of any kind and I have been pleasantly surprised by the response I've received, including several PMs.
In response to RiggerRob, at no point was I looking at getting the M4 for its looks. I just didn't want to buy a container which wouldn't allow me to downsize my main later on. I'm not suicidal and enjoy being alive a lot!
In response to Reginald, I will remove 'swooping' from my profile immediately, as it is something I want to start along with wingsuits in the future.
Today I spoke with Performance Designs, Mirage, and my instructor. Hopefully the results will give most of you peace of mind. I have decided to buy the Mirage G4, size M5, with a Sabre2 190 main and a PD176 reserve. My instructor is confident that the reserve size is fine for me, considering my current performance and the fact I'm taking a canopy control course. The main will keep me relatively safe and entertained for a while, and I'll be able to downsize in the future without having to buy a new h/c.
What I'm flying now is a PD190 (F-111) which is giving me consistently nice openings and landings even without wind (rarely much wind at my DZ), so the Sabre2 190 should make things just a little more interesting.
Obviously any further recommendations are always welcome.
Blue Skies,
Henry
