For some reason Roncer cannot understand that there are not particular market makers for certain strikes. Even in equities this is not so.
Market makers in equities are designated, and make the market in all option classes and all strikes (Each exchange assigns a MM firm)
There are not certain market makers for different strikes. Your brokers rep calls out your bid or ask in the pit, and the MMs respond. Any MMs can respond, not certain ones.
In regards to fill problems, imagine this scenario : Suppose you are trading SPX, and you put in a sell order for an option that has a delta of 50. Well the MM might not be inclined to post a bid for the option because he's hedging with SP, which has a delta of 250. Now if you were buying 5 contracts, it would be easy to hedge, and we have a different story. Food for thought..
