Much of it depends on who you are as individuals. My S.O. is pretty easy to deal with. She has anxiety about riding with group because she doesn't feel she is "good enough." But, when we ride together we just ride at whatever pace keeps us together and interested. We are fairly equal on hills (she may have a slight advantage), I am a lot quicker on the downhills (thanks to my weight "advantage" and experience at speed on my Ducati) and I'm stronger on the flats. After a good downhill I spin until she's with me and on the flats I spin rather than try to crank up wheel speed. It works well for us.
