It depends on what your opponent is up to (stags, blobs, emplacement spam)
In team games I usually do 2X Mg42 and bike and 3 or 4 snipers then go infantry vet 3 dual panzershreck grenadier (3 squads) and blow the trucks or defenses he has while snipers do the Ai job. It might not work very well against stags though, but that's why you tech to panthers or get Pak or two. If see my Brit opponent do nothing but spaming infantry ( if he has 3 LTs you can tell he is up to something like that ) I just go vet3 sniper abuse and punish the Brit for being a noob blobber.
I don't usually play 1v1 but my usual start vs the Brit is 5 pio t2 halftrack and 4 or more vet 3 grenadiers with shrecks if you can, and then get stuh42s to deal with infantry but again then again you are very vulnerable to staghounds, but that's what supported paks or lategame panthers or tiger are for, if you managed to survive. If I still have pios if I can afford it I upgrade vet and flamethrowers for them. Problem with this is that once you loose your stuh's or early game your halftrack is gone and you don't have enough CPs for stuh your grenadier or pio blob is no match for Brit blob. A simple Pak decrewed and turned against you leaves you even more vulnernable to stags and makes the stuh vulnerable to the pak you gave him.
All you need to do is to just simply retreat the pios if you are going to have risk of loosing it, that's pretty much the only micro you do. You just really need to pay attention to them so that you still have capping power.
