Flimsey????? I've been shooting the 2 blade 100gr Snypers for years now and they have held up better than any other head I have ever shot...Not just mechanical heads but fix blades as well. I've been bowhunting well over 20 years and shot all the popular heads out there in that time span and the Snyper's have been tough as nails for me, I've killed 2 this year now with the same Snyper & the same arrow, all I did was replace the blades and kept shooting...I gotta slap some more blades in that one now and it'll be ready for deer#3 as soon as I do.
