Reap, the default mode of a mono-filament whip is as a whip. It comes in a handle where it is cotained until you let it out. It isn't cyber-ware at all. I feel 100% confident in saying that having it in cyberware is entirely unique. This is the first time in the shadowrun universe I have ever heard of one being altered into anything but a handle that holds the filament. I should say that since I had switched her over from a street Sam (page 3) she was always going to use one. As a street Sam she had the strength to use other melee weapons.
Thats why I had whips 3. I wouldn't use a reglar whip, they do somewhere around strength light damage, no where near enough. I just switched the whips 3 for the specialty of whips/mono-whips 2/4, what I had intended to do from the beginning. I mean, she would only use the weapon in the last extreme defense of her life, she needs a weapon therefore that can kill easily when she is forced to use it, and for someone as physically weak as her, its a mono-whip, because of the 2 meter reach, and also because the damage is not reliant on strength. When eventually she bonds a weapo focus, a mono-whip is what it is going to be. The only way to harm a spirit(For her) is an unarmed attack, or one with a melee weapon, or a spell. The damage from a melee or unarmed attack does Charisma (M) damage, the damage from a weapon focus is the weapon's base damage code. The 10(S) damage at a 2 meter reach beats out 3(M) with no reach. The only other weapons that are independent of strength do their damage as stun damage, making it useless as a weapon focus.
Your right though, I should have flat out said that I was planning on using a mono-filament whip back on page 3, but at the time it was unavailible at character creation because it was availibility 24 and the max at creation is 8. Once Folkert allowed the purchase with the paying of the street index, it became availible, otherwise I would have bought it before. I am sorry if that upets you. But it was my intention even before I knew you were planning on playing Johny Mneumonic. i do think there are enough of them in the world, and enough differences between your internal one and my regular one for them both to co-exist.
In response to your "are adepts under-powered?" question, they are what they are. They are specialists, they can be better in one or two areas then a street Sam, but a street sam will be better over all. Its a trade off. The average adept doesn't set off metal detectors, street Sams do. Street Sams need major cash for their cyberware, and they also need to maintain their ware with regular visits to sHadow clinic. Sams need to pay not only for the Ware but also for surgery and hospital stays. Adepts jst spend the karma and get the power point immediately no monetary cost at all. There is just so much cyber a body can take, 5.999 or so, if you hit 6 used, you are dead, no ifs, no ands, no buts(Cyberzombies don't count, not really). An adept can keep spending karma as long as he is living, so eventually he can be better all around then a sam, at no monetary cost, and with no real detection of his gifts through mundane means when he decides to retire. He doesn't need permits for all of his powers like sammies need for their illegal ware.
