Recommendations for blending “kit”

I just got an ounce of straight latakia out of curiosity. Now I’d like to maybe play with some blending. I’m very sensitive to tongue bite and have so few tabacs that please me. Sutliff’s Z92 (Vaniila Custard) is the only one I’ve found so far that can qualify as an every-day go-to smoke. Would appreciate advice about assembling a “kit” of likely tobaccos for a personal blend. I know they sell ready-made kits, but would rather make up my own with some help from the cognoscenti here. Ideas?
