5 card major/weak NT bidding systems
WJO and Truscott are generally separable from your system. They are part of your defense and are more like a "component" rather than a part of your system methodology.

Kaplan-Sheinwold (KS) adopts a 5-card Major approach with a weak No-trump opening, ranging from 12-14 HCP. However, its only strong opening is 2C, with 2D, 2H and 2S all being standard weak two bids. However, reverse Benji can be easily incorporated into KS without greatly changing the one-level openings and their continuations.
