You are correct. Against that outside scoring with your outside defence he'd be expecting to shoot you to pieces, so 2-3 zone would be very risky. In terms of your offence, your inside scoring is pretty good, so either leave it as Base Offence or go for Look Inside.
The defensive match-up is going to be a big headache for you. 3-2 zone probably won't hurt too much in terms of inside defensive match-ups and will cost you rebounding too. Either way, pick your best outside defenders (obviously).
A tough match-up. Good luck!
