RbK 5K Shaft

[EBondo 233]

For those of you that saw this shaft at the shows, and have held it, how does it feel? Because I am going to try to beg my parents to buy me one for my birthday(March) and a RbK 3K blade too. I would like to have some opinions on it. Should I ask for this or spend the extra money and buy the OPS? I am kinda leaning towards the OPS though, considering the comb would cost over 100 USD anyways, and the Int. 5K is only 129.99

But still, does anyone have any opinions? They will be much appreciated. Thanks!
