Supernumery - the OP stated that he turned down the bigger jet previously so it's not an option for him now.
Smokie - we don't know the types the OP is currently flying or has been offered but he states his current type as a "regional jet". An Embraer 145 is 22,000 - 24,000kgs whereas as DHC8-400 is just under 30,000kgs, so how does that fit with your MTOM argument?
As I said in my post above, some airlines don't value regional jet time.
