I have a set in 23 grams and they feel heavier than that - I probably would have went a gram lighter if I was to order them again although I prefer barrel the style in the 23 gram. I really like these darts, they have an excellent finish and feel, I rate the overall quality as good as any other manufacturer. It seems that 95% tungsten darts used to be more expensive than lower percentage ones but I think I paid £14 or so for them, which is a bargain. I also had them in 25 grams but found them too heavy, but I really wanted to try a lighter set. I consider the 23 gram set keepers though - definitely not for trade or sale. As far as throwing them , Scott Waites grips his at the front of the barrel, but I find the center works better for me . It takes a git of getting used to but when they go well, they really go well.
