Hi,this is the first time that I've used this site,and am at a loss,what's the difference between a roller and a tumbler,as I have a small kit of west of england tumblers only seven at the moment.I hope that you's will excuse my ignorence,but untill I got on the computor I only knew of the average breeds like fantails and the like,but am very interested in the rollers from what I've read,but I don't think that I've been able to recognise the differences yet.Could some one help me here tatts
