OT abit, but for those looking for them, after quite a lot of trawling I managed to find torx+ drivers from Wiha.

A hint when ordering, the drivers themselves are quite light but the order was bulked up with the free catalogue they sent with it, and I wonder if my delivery fee was bigger as a result. So you might save a couple of %curr by unchecking it from your order.
