Very good, Simon. But all too often those using the radio and a transponder forget TO KEEP A GOOD LOOKOUT! too busy looking down at all the gadgets in the panel. If you rely on your radio and transponder and ATC to look out for you and keep you clear of other traffic, you may have some uncomfortable encounters, and that is not necessarily with gliders. I suggest you go for the IR and fly only in controlled airspace. The rest of us are required to keep clear (unless we have permission) and so the uncontrolled airspace has developed horrendous pinch points.
