Even if you normally only ring on six bells, the occasional foray into ringing on eight or more bells is not only a welcome change, but also helps develop rhythm and a greater understanding of the three positions in minor and adds a new position:
On eight bells, the 2/3 position (with a gap of 3) becomes much clearer, on 10 bells the 3/4 position (with a gap of 5) becomes clearer etc.
When starting to ring on higher numbers you don't have to stick to the standard pairs. It is much easier to establish a rhythm if everyone rings coursing pairs initially (e.g. 1-2 3-5 4-6 7-9 8-10). The rounds will feel a bit weird and lumpy at first but you'll soon get the hang of it.
It is important to practise these positions until they become automatic. This requires you to do your homework.
You might look like the nutter in the park, reciting numbers or mantras or twiddling your thumbs whilst sitting on a bench, but it works! Online ringing simulators also help as they will introduce you to the rhythm of the different positions.
