I’m personally a full clip in the summer because I think it’s looks better for shows. And a trace clip for the winter months because they still have hair and you don’t have to blanket them that often till when the very cold days.
I'm personally a fan of hunter clips for when the horse is in fairly hard work, especially because mine are all turned out for a good part of the day. A hunter clip leaves the hair on the legs and either the whole head or half the head. A saddle patch is optional.
Clips vary depending on weather, amount of work, and sensitivity.
For horses who do minimal work, but still work, in winter/cooler months, people often go with either a bib clip or an Irish clip. For more consistent work/often worked indoors, a trace clip or full body is usually better. More sensitive horses do better with Trace clips because it leaves a layer of hair between your saddle and their back, as well as the choice of leaving an area of where your leg gets put on.
For the process of clipping, I personally go in three stages.
1st: Clip the larger area with bigger, chunkier clippers.( Most of the time it also means louder clippers.)
2nd: Clean up edges and even things out with quieter, smaller clippers. I usually use these close to the head and on the legs.
3rd: I take smaller, usually wireless, clippers to clip the face and around the hooves.
Clipping is definitely a process for the patient, but worth it in the end!
