I scripted some mousewheel control for me, because me fingers feel pain 
The script do the following,… if u rollback u take the mainweapon (weaponbank3) the next time u rollback u are reloading.
The first time u rollforward u got the syringe and the second time u get the medipacs,…Probably simular to the other charakters,…
Here my script
bind mwheeldown “vstr specialtoggle01”
set specialtoggle01 “vstr weapon11”
set weapon11 “weaponbank 1;weaponbank 2; weaponbank 3; set specialtoggle01 vstr reload; set specialtoggle02 vstr weapon9”
set reload “+reload; wait; -reload; set specialtoggle01 vstr weapon11; set specialtoggle02 vstr weapon9”
bind mwheelup “vstr specialtoggle02”
set specialtoggle02 “vstr weapon9”
set weapon9 “weaponbank 5; set specialtoggle02 vstr weapon10; set specialtoggle01 vstr weapon11”
set weapon10 “weaponbank 6; set specialtoggle02 vstr weapon9; set specialtoggle01 vstr weapon11”
//Wheelmousealtern.weaponsscript
set Alternweaponzoom “unbind mwheeldown; unbind mwheelup; weapalt; bind mwheeldown weapprev; bind mwheelup weapnext; set nextAlternweaponzoomtoggle vstr Alternweaponzoomoff”
set Alternweaponzoomoff “unbind mwheeldown; unbind mwheelup; weapalt; bind mwheeldown vstr specialtoggle01; bind mwheelup vstr specialtoggle02; set nextAlternweaponzoomtoggle vstr Alternweaponzoom”
set nextAlternweaponzoomtoggle “vstr Alternweaponzoom”
bind mouse3 “vstr nextAlternweaponzoomtoggle”
Probably u try it and like it (i hope so). Perhaps u catch the idea and integrate in ET. I thought try it now there is a chance for it 
AHhhh yes and ET is GREAT, it will be one of the best shooting games ever The grenphysik is nice, the gameplay (building things) and the sound of the weapons, the MG´s (very nice like in CS or MoH) and the skillsystem,… and,… and,…
