Baaaaad idea! Since combat rarely lasts more than 5 ~ 6 rounds, a
spellcaster's combat power is more dependant on his maximum spell level
-- ie. the number of options he has -- and caster level -- ie. the
magic 'output' per spell -- and less on the number of spells he can
cast per day. By multiclassing Sor/Wiz you will have low caster level
AND lower available spell level -- a very poor choice.
If you MUST multiclass between sor/wiz, take one level of sorcerer at
1st level, then play a specialist wizard for all other levels. In that
case, you will be one level behind a pure caster -- which HURTS -- but
will have access to all wands and scrolls, which MIGHT be worth it. I'd
still think it a poor trade, IMHO.
