I'm surprised you don't like the 6P. Keep in mind that you can do a lot with it - P60/P61 lamp assemblies, KT1 turbohead. If you want a smaller light then the following might not interest you, but you can add an A19 one cell extender and then run a P90/P91 lamp assembly, with the choice of installing a KT2 turbohead for increased throw. In the not too distant future, SureFire should be making the P60L (LED) lamp assembly available for purchase, giving you yet more options. Not to mention the numerous third-party accessories.
