To the O.P.,

I have used the spitfire 125's for many years with great results. The position of the blades after you removed the arrow are not a reflection of whether they deployed or not. When target practicing if the broadhead fully penetrates the target but the shaft does not the sudden stop will often close all the blades. but inspection on the entry side will show that the blades did indeed deploy. As for the swackers I think they would be a great head to use and I have thought about trying them myself.
And my apologies for getting off topic in the above post.
