I agree the roadside bit, just replace it and repair later in the comfort of the homeToo lazy to repair mine especially at the roadside so just stick a new one on.
I keep repairing them until I get a hole too big to repair. As for patches, I get the repair kits from Wilko's, about 79p and find that they are good quality.
So, how do you get the patch off without ripping the tube, Jimbo?...When there is a puncture right next to an existing patch, the patch comes off and I use the long rectangular patch to cover the old and new holes
