Shedding sheep breeds

WiltiPolls and Wiltshire Horns:
Wiltis are very good wool shedders.
They have all the advantages of full shedding - no shearing, crutching, mulesing, flystrike, or lice, no shearing shed, and no hassles getting shearers.
They are good mothers, and have better-than-average twinning percentages.
They are intelligent, as sheep go - "the thinking man's sheep".
A clean shed Wilti ewe is a very nice looking animal - "Venus arising from the foam", if you are really keen!
Wilti breeders are often passionate supporters of the breed.

The down side to Wiltis:
Wiltshire Horns and WiltiPolls don't grow as quickly or grow as much meat as some other breeds. Some say the breed has "no back end".
Wiltis are strong and can be hard to handle, so they are not an easy 'retirement' option. A stock agent's comment - "they always draw blood in the yards".
They can be hard on fences, like most 'cross-breeds'.
Wiltis are an English cleanskin sheep, not bred for heat and poor conditions like Merinos and South African sheep.
Wiltis are seasonal breeders, mostly lambing around August. This makes it hard to get lambs to breeding or slaughter weight on pasture that dries off in late spring.
Wiltshire Horns, obviously, have horns. Horns can be useful "handles", but most farmers prefer polled sheep for the safety of the sheep and themselves.
WiltiPoll shedding can vary - they need a lot of culling in the breeding process to get rid of the wool gene which came with the poll gene.
