I beg to differ, what you need is the solid handling mid sized Texel lambs you can pick any amount up for between £2-300.Alot of those very plain texels out of mules around the Stirling markets, big frames, no giggots, a think you'll have to buy afew real good texels 1000+ to see a difference, but abit beltex will make a difference also, the beltex x texel aren't cheap either.
