Simple answer is find somewhere that stocks them and try them out preferably on a range or practice ground rather than an indoor bay. It might be you like them and the way they feel and the ball flies or they won't suit.
They were my first set Nev.....There good bats and they can be had for handy money now id say....You should still be able to buy them new.....They have been replaced twice with Di9's and Di11's but these have the new conforming grooves and are basically the same club dressed up.....Get the Di7's if thats what you like.....You sont be disappointed....
