Wow, you know your stuff! But I'd rather stay away from hybrids since I haven't perfected my swing with the one I own. I'd prefer to own just 1.
I hit my long irons well, considering my low swing speed and low skill level. I found that if I try to kill the ball I always mishit, so I slow my speed down and get better contact and doesn't have much spin. My 3 iron totals at about 185, which I am happy with, and I am ok with a low launch, as that theme is common in all my clubs.
My PW is 47*, next club is 50* (given to me by a buddy when I first started, totals about 115yds) and after that is 56* (for <105yds). I dont want a higher lofted club, because I am becoming more and more dialed in in 1/2, 3/4 etc. with my 56*.
My driver is a tommy armour 460cc, and I hit about 220 total. I dont feel comfortable hitting a club with a bigger face off the deck, which is why I don't hit hybrids or woods well. I'd prefer a low lofted iron to fill the gap, but dont know much about good 2 irons. Hybrid doesn't travel much farther than my 3i.
