I bought these as I was looking for something like a 7A stick but with a bit more length and weight to it.
Before these I used Neil Perts signature Oak sticks from Promark for years and got used to the weight so using regular 7A sticks always felt weird, almost like drumming with balloons or sticks made of paper or something. Transitioning to these was no problem though - the extra length makes them feel a lot heavier.
They used to feel like the perfect balance between weight and reach. Not to heavy, so your stamina will last longer, while still having weight enough to give you adequate impact force for heavy hits when needed.
The extra reach compared to a 7A might not seem much but does quite a lot.
I've been using them for about a year or so but must admit that I recently started feeling they where to long. I kept hitting my kit element beyond the intended point of impact and had issues adjusting the kit to compensate for it without feeling awkward.
I'm very tall, which might factor in here.
Despite that, I consider these one of my all-time favorite sticks and always keep a pair or two around.
