Hey so what's your middle single coil ? And what bridge single coil are you replacing ?
It helps to know that so we can get you back in the same ballpark.
I've heard really nice tones out of a pearly gates bridge pickup split with a middle, modern single coil(10k). I'd say it was very "strat-like" and in fact I played a lot of the bluesy stratty songs (Kenny Wayne Shepherd, SRV, Hendrix) with that position and it was IMO very convincingly Strat-like.
I am also currently in love with a JB split with an antiquity single coil middle. It's a very groovy sound but I'm not sure how to describe it. The JB also sounds VERY good in my opinion, in Full humbucker mode in the 2 position with the middle single as well. Almost has a PAF mojo to it. They're both such good tones I can't decide which one I like better so I wired a push push pot to split the pickup instead of auto split. That's about been my experiences and both have been lovely
