Ours is inherited too so I've no idea how old it is but it has a similar sized pal on another wall. We moved in last October and I did a bit of a tidy so we could walk past without being ambushed. I then gave them both the January prune as advised by the RHS. Now flowering has finished I shall tidy up some of those stems on the far right and then leave them alone till the July prune is due.
They are fabulous plants with a lovely perfume. We like them so much we bought a white one this weekend for a pergola we have yet to build but it was perfectly formed and covered in blooms so we grabbed it while we could.
Dave's wisteria on his pergola look very well trained and pruned so you should be fine with two if you look after them well.
