Aside from the cost, there are precious few of the types you mention in the UK. The UK rules mean that operators choose twins for their medium heles. One of the main differences between fixed and rotary is the impact of positioning costs. So, unless you use a hele that is close to your operating location, you will pay a lot of positioning cost.
Assuming there is a good reason for using a hele, it might be a good idea to look at it from the other end: what Heles are based close to you?
