The low pin is fairly strong, near as I can tell. It should be around 4"/4.25" pin to PAP. With your release, that low a pin can be early, but you have good ball speed. As I said, I think there's a difference in length but it's not huge. You are probably right on the cusp of usability.
In fact, the thought occurs to me that if they have the same surface, maybe, once you get them settled as to how each reacts, you might want to add some difference with a surface change on the higher pin to maybe 4000 grit Abralon.
Just a wild thought.
Funny - add some polish to your Cell and you have a 3 ball arsenal ....
