alfieb,
the ifindforu is a little different to most on the site for sure. i find it very good but use it more as a now and again sort of special occasion base (not for midweek). the last stage of adding the seasoning (must be rajah) and getting the adjwain seeds proportion right for your taste buds are the key bits for me.
know exactly what u mean on the 1 out of 7 on the TA's creaminess. my take is that the one i like has more garlic, tom puree, lightly spiced (less cumin, more paprika) and has a high proportion of onion in the base. the oil is their but not too much.
