Not tried A41s , but another Road 6 fan , all the grip needed in the dry. The wet weather grip is the reason I got them though , so confidence inspiring , riding in the wet/ cold is fun. Good enough mileage , bit pricey mind .
As above you don,t need to swap a pair , I have done it loads , but it is nice to do if a certain combo hasn't been tried before. Some combos don't work well due to different profiles ( not the numbers on the side ) even from the same maker but a different tyre. More usually a problem moving to sportier tyres , mid pair , though , with a higher more triangular shape to make the bike turn quicker at the expense of straight line stability , throwing out the balance front to back.
