I'm running a triple with bash and 22/32 chainrings too, but with an 11-36 cassette. I recently switched to a mid cage rear derailleur--even though technically the 32/36 combo isn't correct for that derailleur. When I installed the new Shimano 10 speed mid cage derailleur, I used the same length chain as with my triple derailleur, and I was surprised to see that the big-big combo did not have the derailleur very stretched out ( it looked like it was at about a 45 degree angle), so I thought it was fine. Yesterday, I went off a 12 inch drop, and the rear of my bike exploded.
When I extracted my rear derailleur from the spokes, I discovered the cage with the pulley wheels, which is normally straight, was bent at a 90 degree angle. The chain was jammed between the spokes and the (new) cassette so bad, it took a lot of jerking and pulling to finally free it. Needless to say, all my drive side spokes were ruined. I removed the chain and derailleur, and then I walked 1.5 hours back to the TH. I wasn't able to determine definitively whether I was in big-big, although after I removed the derailleur, I released 8 clicks from the rear shifter before it bottomed out, which suggested I was not in big-big.
I just installed a new long cage Shimano derailleur, new chain, new derailleur hanger, and eight new drive side spokes. I was never able to get the mid cage derailleur adjusted properly, so I thought the shifting was terrible. If I adjusted the shifting so the low gears were perfect, then the shifting for the high gears was sluggish, and if I tightened the cable to get the high gears shifting properly, then the low gears would overshift slightly.
