SuperStroke CounterCore Weights

Worked exactly as described and fitting couldn't have been easier. The inclusion of a dedicated key was a nice bonus - but not really necessary. Both the original and new tops can be removed & inserted with a standard sized Allen key. Perhaps the price could be reduced if the key was not included? Went for the 50g weight - and though I can feel the difference - might try the 75g. Overall - very pleased with the product.

I feel much comfortable with the 25gr version (50 feels a little too heavy).
