TKO help

[66fstbk88]

After looking at all my options, Ive come down to going the TKO route.
I was looking at the new TKO 500 and they have a 10 and 26 spline input option. I'm confused about is, what is the difference between between a 10 spline input and 36 spline input?
I know a stock T5 like the one I currently have are 10 spline input but every time I hear bout people having TKO's in their classic, seems they always mention how they had to convert to a 26 spline clutch as well?
Is one better than another?

I was thinking about a TKO myself a while back. The 26 refers to the spline count, and requires a 26 spline clutch. The 26 spline is stronger than a 10 spline. If I do go the TKO route, I would get a 26 spline.
