I bought a full size Solitaire a month or so ago, and I can't speak highly enough of either the product or Roger's service.
The bat I bought weighs 2lb 9ozs, has dead straight evenly spaced grains (8 from memory, but at work just now so can't check!), and lots of wood on it. Pick is light, but the noise it makes when you hit the middle is incredible! First time I used it I got 40, with 9 fours!
For £100 quid you can't go wrong, and I'm sure the junior bats will be equally good!
