I will use Wyeast 1099 usually (it's an old Whitbread one, not the 1098). I used Wyeast 1187 for the Morrell's (as per Make Mine A Magee's! : MORRELL & Co : BITTER 1889 (oldbeersandbrewing.blogspot.com) ), its spawned from an old Whitbread yeast apparently (as is WLP022 that I know some use) but does have a reputation for not starting (not for me!), and 1469 for the Tetley's (Make Mine A Magee's! : JOSHUA TETLEY & Sons , X K BITTER BEER 1868 (oldbeersandbrewing.blogspot.com) ) but that is very enthusiastic and isn't clearing well yet (early days). I used WLP002 for the Amber Small Beer but only because it needed using up!
