I have been made to feel very welcome and have received invaluable advice already. I use a cheap Chinese eBay catapult and intend using it gingerly until I can afford something stronger. I like the Chinese style as they don't take up much space and changing the bands is a doddle. At the moment I practice at 5m and 8m and use pebbles and chukky stones. I've tried Mint Imperials and various boiled sweets as there seems to be a town wide moratorium on marbles. I wouldn't want to be hit with a mint imperial.
