Chev (going a little o/t here), but what about Llanarth, Parc and Nebo lines? My wee man has all 3 in his breeding. And Kentchurch (might have spelt that wrong!) aswell.
Lou, dunno where you bought yours from but i've never found them to be so cheap!! the stud i bought from has 2 foals just now, they will be sold when weaned and she's asking £1500 and £1750 respectively for them.
steevielee, as part of your research, go visit some studs. see what they do and what temperament their horses are. I went to a few when horse hunting and the stud i chose my Kez from seemed to have a very laid back, happy, easy going bunch of horses. At the second place i visited, their D's seemed a little more, shall we say, spirited!! very nice horses but certainly more buzzy.
