They look good mate,I like the 3rd and 4th one on the top row,going to give a natural a go first though before buying as I don't know what shape would suit me having never had a catty before,looking to use dankung tubing as I read they last longer and are a little less hassle to fire,what sort of ammo should I be using for some 4070 tubing,or would I be better of going with some lighter tubing to start and doubling it up.
