My brief take (rereading this as I finished the post, these are famous last words P:) )
However, please bear with me even if things seem a bit roundabout. (I don't have a clear idea where you are at with sailing, so some stuff may sound basic, but some stuff that did sound basic to me when I started, is stuff I only now begin to understand...)
My first take on this would be that 10 knots should not be anywhere near where you'd want to reef. When I started out, I used a hand held wind meter from SKYMATE, to get a handle on understanding exactly how much wind was actually on the water (compared to forecasts, which are never comparable to the moment-to-moment wind on the water).
The color and roughness of the water and the size and shape of wavelets or waves will tell you most accurately how much wind there is, and you can even see it coming, as when dark patch of water shows you an approaching gust.
I used that anemometer to gauge my own estimates, but now I don't need it any more.
If your figure of 10 knots is actual conditions (not forecast, or nearby land-based stations) then you should simply have fun with full sails. Gusts up to 15 knots you deal with by some of the techniques in the Basic Concepts thread. A boom vang really helps, because with one, as you let out some main, the rig depowers; without one, it can actually power up as the slack in the main will let both sails take on a fuller shape.
With the vang that effect is gone and I've noticed how that improved control. Likewise, if you have older sails (I forgot whether you mentioned that already) upgrading to new sails will allow your sails to be trimmed flatter, also depowering your rig and increasing your range.
I've never bothered with a gauge for the angle of heel. It's quite simple. If there's little wind and the boat is barely sailing, I let it heel to leeward. Around 3-4 knots, I'll try to sail it as flat as possible, and above that, I'll sail with just enough heel so that I can feel if the boat is loaded up.
If a gust hits, the boat can heel further, but I generally try to limit the heel by sitting out further or hiking harder. I don't have a precise target angle, or a set period to bring it back to level. I often luff up a bit to gain some height, but if I'm by myself or don't want to work that hard, I just spill the wind by letting out the main (mine is practically never cleated).
But there's an effective limit: once the boat heels so much that water gets onto the side decks, I'll definitely depower the rig, but letting the main out or luffing up or both.
I don't know where you are sailing and how critical it would be to able to reef, but I wanted to give you some feedback on the conditions you claimed you experienced first.
I'll put some thoughts on setup in the next post.
