Doubling the Eurodollar Dec '07 position

Paid 94.915 for another £100/bp of Dec '07 Eurodollar (I already had on £100/bp at 94.965). I like this trade, and want to be big enough to make some decent money if it performs. A reasonable worst-case scenario is that more hikes come along and I take a 100bp hit, so £20,000, which wouldn't be ideal but would not be a killer.
