Well yeah I was thinking I could use the T$ either to trade for cash or play in SnG's which is what most of my bankroll has been funded from. (been on a roll with these)Depends on your BR, if $200+ is a substantial increase then take it.
It's always worth it, take a shot!!!
It's also important to think about whether or not you'll play your best. You'd have to play fearlessly to make the most of it, if you'll be nitting it up to go for the min cash, it's not worth it, just take the $215 until you feel you're ready to play this kind of buy-in.
