When I first got the TEN I used Oxford throwovers and found them fine. The heat shields on the Ten are quite robust and do keep the heat away from the panniers, BUT even on other bikes I have always used a ratchet strap to really secure the panniers onto the bike and not relied on gravity to keep the straps between onto the seat.
'Crusty' has made some rails that go from just underneath the rear carrier to the rear passenger footrest brackets which will substatially reinforce the back end of the bike and give you something to secure the panniers to. Now he has his new panniers I know he has a pair of these bars spare. Hint Hint.
...........and I've seen just how much he can carry on his bike with soft throwovers!
