The Dragon-F is offered in 2 versions (medium and hard):
Both versions are absolutely identical, except for the degree of hardness (the packaging is also identical).
The rubber is tacky as usual (quite strong in fact) but the open pore underlayment is not made by Friendship itself and is therefore unusually elastic, slingshot strong and fast for this brand.
The slightly softer version of the Dragon-F is slightly slower than the harder ones, but is also easier to play.
The weight of this rubber is in the mid range.
The processing quality is excellent, the price-performance ratio is also....
