Not either of them, but yes definately there is.

Wilson is actually producing putters with backweights already. And since you're in the UK wilson is pretty popular (i think) maybe you could demo one at a shop.

Otherwise you can play with back-weighting on your own. Get about 4-5 quarters to start with and tape them to the end of your grip on your putter and see how you like the feel. Keep adding quarters until you really make some SMOOOOOOTH strokes.

Its funny, my g/f is the worst putter in the world. I let her swing my putter when i was experimenting with backweighting and i couldn't believe how much improved it was. It was seriously like an F versus a C if i was grading her stroke.

I ended up with about 8-9 quarters. When i get my new putter i'm going to backweight it with a screw probably as the balance certified stuff is expensive.

I've also heard someone who made a backweight that is adjustable via up/down the shaft without removing a grip and it locks in place so its USGA conforming. Its not out yet though.
